hi guys so I’m just gonna list what’s up or what I’m worrying about on my grow.

My plants are 5 week into veg i hv 6 in a 1.2x1.2 tent in 10 L buckets, I’m worrying they need turning now as of my space and the doubleing in size. There about 12” high now and bushy due to me LsT them,Soil I’m using coco lite11.

But don’t know if my plants are ready there quite dark green, abit droopy, some hv little yellowing on ends not many just at bottom, I’m using a dripper set so don’t know it I’m getting feeds correct abit all over plc.

I never hv run off as I though I was over feeding or was told that so I stepped back a little now Iv been told I’m not feeding enough, they get about 1 litre a day, should I be making shore I get run off iv not flushed them once in the 5 week can see salt build up in collected trays at bottom is this bad.

Thx I’m may be paranoid but rather be carful and grow a good grow thx I also hv star dawg cooking if that helps.

They look like they are getting too much food. Definite signs of toxic salts buildup which will only get worse. By mid-flower you will have hard, crispy dying fan leaves for sure as tehy are already going that way.

Your watering system doesn't seem to be doing a very good job but I can't really tell not being there.

Sounds like they need a flushing to wash out extra salts then a wet/dry watering cycle with 1/4 strength nutes to start off.

A shop vac would be handy to empty the trays as they fill during a flush so the pots can stay in place.

Really dark green is another sign of over-feeding. Do you know what ppm you are feeding and if tap water how hard is it? It's minerals add to the salts overload as well.

What media are you using as that makes a difference. Peat based, coco or real dirt?

:peace:

Hi buddy wow thanks for the great reply man.

Ye so I’m use it coco lite like a soily colour with white tones stones in it.

I know iv added about 10 mil more of each food type the feed chart asks for it my 90 litre driper tank.

They are going crispy abit on the ends your correct mate mate some about yellowy one plant is kind of going light green to yellow now rest are fairly dark brown.

I’ll look into a shop vac if not I can do one at a time put 3 times the pot size of water through and just lift pot and keep emptying.

I don’t know my ppm buddy only hv a PH tester unless same thing and with all my feed iv added for flower stage and tap water I’m getting a reading of 6.1 then that will change as it goes through coco I’m guessing witch I cannot test as I never get run off I do give them like 1700 mil a day once a day 1 hr after light comes on.

Some pics of what u just asked me my feed iv got in the tank 220mil of each flower section. And ph reading

Your feeding them far too much nitrogen. If you flip the switch now they will triple in size. I'd give them just PhD water for a week or so to try and flush some of the nutrients out of the soil then start with your bloom nutrients. Remember when feeding cannabis that less is more. I know it's hard to hold back and not feed the girls but too be honest you will end up with much healthier plants if you do.

Right there tells me you are feeding way too much. Not sure what brand of nutes you use but if I followed Advanced nute chart to the 'T' I would fry any strain. For growing in soilless I generally use around 1/2 the recommended amount unless they are growing like crazy then may go to 3/4 but I skip feed and use RO water only. Even then some plants will burn.

If you are going to constantly water them with the nutes in the feed water you should be using about 1/4 the max amount from the start and stick with that only upping the feed if you see older fan leaves going yellow and limp. With toxic salts buildup they go yellow/brown and get thick and crispy.

If you are using a 3-part nutrient system drop the Grow part and use half as much Micro as you do Bloom so they use up some of the stored N. As N is a very mobile nutrient the plant can steal some from older leaves if it needs any. It's a method called Lucas Formula that a lot of growers use.

When flushing a bunch of pots I found a shop vac to be very useful. The water drains really slow so I'd just keep adding more water to the tops and sucking it out as the catch pans filled up. I was only doing two plants in 4gal pots but they were in a ScroG so couldn't take them to the bathtub and do them in there. Got a little pissed one night and decided they would grow better with lots more feed and two days later started to fry. :)

PPM pens are cheap and worth having tho not as necessary with soilless as hydro. Last a lot longer than pH pens too. Bottle of calibration sol'n is about the same as the stuff for pH calibration too.

I just looked at the feeding chart you posted for Remo nutes. That mix is intended for a hydro setup and not for continuous feeding into pots. With pots anything your plant doesn't use builds up in there until it's way too high like your situation. AN does the same thing which pisses me off as I run into newer growers all the time doing basically the same as you and having the same issues. How hard would it be for them to come up with charts for growing in soilless.

If you can give them a good flush and cut back on the nutes you should be in for a great harvest yet.

Here's some reading material for you. Exam in 30 days. ;)

I found a great spot to download FREE POT BOOKS. I downloaded a grow bible first and got lots more. Books look great and complete like the real ones I have here. No web site but just a page of links. Just right click on what you want and then "Save Link As" to download so they don't open first as some are 50+ megs. They got lots. Enjoy.

Man I cannot thank u enough what a help and guy to tell me all this much respect for u buddy as I was going out my wits.

Ok so flush I’ll look into how to do this the easyest way, yes this Remo stuff if for my dripper set up not hydro or by hand so iv added what it said like u say that salt is building up so much I just need it all out ASAP tonight. How do u flush or recommend buddy I carnt get to my bath or out either and need this done ASAP so vac no good for me.

I’ll empty the feed tank later and wash it out then add 90 litres of water and 1/4 of the 210 mil flower feed chart says to give so like 60 mil of each in the 90 litres that’s way help my salt problem too I’m guessing. Also all use less micro so take that down to 30 mils per 90 litre.

That grow nuts u say don’t use any even in veg as flower it is not used anyway just checking thanks.

Ye your experience u recon my problem is all down to the salt build up and nuts over feed resulting in them not been able to take up the right amount needed.

I’ll hv a read of those thanks man.

Can you raise the plants up enough to set them over a pail or something to drain into? Be a bitch to be taking water out of the trays with a turkey baster or some such. Still have to get the waste water out of the pail too. I also have a little drill pump that would be good for that. Cheap too if you have an electric drill. Empties a 5gal pain in a couple minutes.

I'm pretty certain that it's overfeeding and salt build up in the plant's leaves. If left alone you are going to have nasty dead crunchy leaves getting worse as flowering progresses. Was happening to me and I wasn't feeding near as much as you have been doing. Turns out it was my really low RH causing my plants to suck up way more water and nutes than they would had it been if the RH was in the proper zone for the temp. The higher the RH the slower plants transpire and you can run higher ppms. When too low you need to use way less nutes. If I can get a portable A/C unit to manage heat and humidity I'm going to run a sealed flowering room with CO2 and keep that RH right where it needs to be.

As I'm in the middle weeks of flower now the low humidity is a good thing. :)

You don't need the grow nutes now as they are all topped up with N and that's a lot of your problem. Micro has enough N in it for your needs the way things are now.

Ah sweet thanks again man, so I’ll ditch that some, I carnt use out where it is I really need to just get this bang on next time and try solve this by 1 full week off feeding PH water.

I wanted to munction this u you buddy I noticed last night that a week again I looked at the bottom of my pot and all roots where nice and white some now hv gone brown and skinny witch is root rot if I’m right only 2 plants that I can tell as of now.
At 5 week there ain’t no white roots at the bottom of my plant defo a root problem.

I use coco perlite and iv never had run off so there not drowning for shore. I use my dripper kit that’s a tank 100litre with a length of black hose with a blanking plug on the end, I hv 6 Hoses coming off my main hose from tank/pump going into my drippers in the pots next to the main stem I hv 1 air bubble mechine thing in the tank too, emmm am I getting that oxygen in there.

I’m really stupid feeding by hand is so easy this is just new and hard to get ahold of, so how my feed as gone is not once has the feed emptied the tank when it’s got say 30 litres form bottom iv just topped water back to 100 litres and added the nutes not really bowing what I’m putting in but a good guess to what chart asking. What a cook headed noob I am

Tank may take 2 to 3 week to empty 100litres into 6 plants bad I know so what I think is happening is shits going stale in there and been fed to the plants maybe what coursing root rot not exp here so just a guess.

Really sorry to be so stupid and dumb and posting taking your time fella sorry.

Pool shock (calcium hypochlorite) will help with the root rot. In my bubble system I mix 0.5 gram to a gallon (UK gallon=5 litres) PhD water and add from that diluted mix 1ml per 5 litres to my buckets every 4 days. Calcium hypochlorite is also a micro nutrient that plants use. It's a prevention though and not a cure for root rot.
Too be honest your plants look healthy in the pictures. They don't look stressed at all.

Thanks buddy ok I’ll pop to the shop and grab some stuff the help with the root rot see what they say. Also emptied my dripper tank and fully pushed 5 litres water through the plants better than nothing for now till I get to what’s coursing this problem.
If it’s my tank and stale nutes that’s the problem I may just feed water a.m. for a week see what happens.

Are you talking about roots coming out of drain holes in the pots or is there a tray of nutes they feed from below the pots? I'm a bit confused about your setup other than you feed them with a self-watering system with Blumats or something like it.

You can still get root rot without runoff if the root ball is kept saturated with the only oxygenated liquid coming in at the top. The moisture in the lower portions of the pots gets depleted of oxygen and the bad bacteria love that.

I think you might be best to allow the pots to dry out once in a while so the plants use up all the old water and allow air into the roots.

If it's just roots sticking out the drain holes they will die and that's normal and even desirable. That's why the smart pots are so popular. As the roots penetrate the fabric the tips die and the main roots branch out like lower branches on the plants when you top them. Makes for lots more fine feeder roots that spread thru the rootball.

I wouldn't be dumping a bunch of bleach in your plants. Those light green grow tips show that your plants are growing fast now so things are probably OK.

I didn't suggest bleach OldMedUser.

I don't know if it would effect the taste at all but plants use chlorine to help them grow but chlorine is used in swimming pools and hospitals to fight bacteria and such.

Hi oldMed thanks buddy great advice again.
My set up is a drip irrigation system consists of a tank, pump, hoses it a passive system I think does not recerculate comes from tank into pots. Weird thing is they ain’t been getting fed that much really 700 mil to 1 litre a day. I have 10litre pots with a tray under neith that is there to catch run off if any but iv never had any run off makes me think not been fed enough.

Also yes it’s just what I can see at the bottom in the holes all dry not wet so many be it’s nothing and there just ain’t roots there, coz there’s nothing white for shore, iv noticed the nice new growth too so I guessing there working nicely now for some reason so I’ve run 6 litres of water through the pods, emptied my tank and cleaned it out also got a ph pen and lowered my feed by half the amount and more.
Just letting this water soke up for a day or 2.
I also gonna up the feed so I get run off and then see how things gonna move to 2 litres a day see how it goes, if the soil don’t bet out on top I’ll lower feed again if that sounds good enough.

In my tank I had brown gunk in the bottom all settled that’s a problem in the tank for shore. So I need to make shore this stuff is been used in a few days so it cannot settle go stale.
