Hi Guys,

Got three easy ryders on the go (link in sig), they have had a stressful life to say the least, and the big one (The one with the problem) has lost many a leaf due to dehydration.

She has turned a lot paler/yellower (i'm colour blind so it's hard to tell lol) than the other two, which seem to be a nice dark green. I watered them all today with plain pH balanced water, and took some pictures.

At first i thought it might be heat stress or light bleaching, i moved the light up quite a bit but it doesn't look like it's made any difference, and with it being so far away at the mo, many lumens are being lost.

I had a look at deficiency guides, but i can't pin it to any specific nutrient deficiency..

If anyone has any advice, it would be greatly appreciated.

Many thanks :)

I think it is root bound, but there's not really anything i can do, as there's no space for a bigger pot, plus there's only 2 weeks left.

I think they may have got slightly greener but not much. What would root binding cause to happen exactly?
 
some yellowing is normal however the entire plant speaks more of nute uptake issues. In some cases the soil ph has gone out of whack and caused lockout of certain nutes.

Root bound is not something that would cause yellowing. i have seen large plants grown with very small root masses as long as the available Nutes are there there will be no issues.

Do a run off
PH test and ppm test

I pH tested the run off the other day, it was within parameters, and i have been carefully checking pH every time. Plus all the plants get the same water so if it was pH i would of thought it would have effected all of them.

Isn't ppm something to do with co2? I've got no way of checking that unfortunately :(

I'm wondering if maybe it is some sort of deficiency.. i've only been giving 1ml/l grow and 2ml/l of bloom every other watering. It's only happened to the massive one so i assume that one would need the most nutes, and they have all been getting the same, so it may have needed more than it's been getting.

I watered it today with 1ml/l and 3ml/l and 1ml/l of root juice as well, so maybe this will help..

The whole plant starts to droop and discolor. The leaves quickly dry up and the whole plant dies. Once a plant is rootbound and dying, it is very hard to save it because the dying plant can't survive trimming the roots and repotting. It happened to our last mother- very sad to have a plant dying with nothing you can do about it but watch. :-(

Shit man, this is exactly whats happening to this girl, she was droopy today on some of the fan leaves, and the yellowing and the leaves seem to be very dry and getting slightly crispy.. Is there nothing i can do, if this is indeed the case? A lot of people seem to say root bound plants doesn't actually cause this, i mean everyone's seen that picture of the massive plant in a small pot that looked quite healthy...

What will this do?

It might be good to point out, every time when they weren't watered in time (check my gd if you need more details) the big one was the most droopy, and other times the other two were fine, but the big one had used it's water up a lot quicker, and even today, the big one needed watering and the other two were still damp.

I'm going to be so gutted if this one dies, she is budding up so nicely now and only 2 weeks left, and i'm proper proud of my lst job, all the buds are at the same levels so they are all getting as much light as possible.. all for waste possibly :(
 
I'm not 100% on the root bound. It looks more like damage from a pH fluctuation. One bad watering can really throw things off. Specifically you look a little short of magnesium, maybe phosphorus as well... not easy to tell though.

If the pH is in check, and has been, then a little magnesium will go a long way.

Things have gotten worse.

I watered the big one last night with a decent supply of nutes, and went to water the other 2 today - the big one is getting worse, it's so droopy (perhaps over watered?) and now the one i call the retard (it's had really deformed leaves since the begging, but was growing fine apart from that) has started showing the same symptoms. It only appears to be the upper leaves and towards one side at the moment, but it doesn't look good at all. Only one of them looks healthy now. Also, i checked the pH of the run off of the retarded one a second ago.. 6.0! I really don't know how that happened, i pH balanced the water last night to 6.7. I mean, this could be even less than 6.0 as my ph testing kit only goes down as far as 6 and it was yellow.

This is really bad times, i'm proper stressing over this, i don't wanna lose a shit load of potential bud. I'm going to wait untill next water and water with slightly higher pH water to try and get the pH balance back, but i don't even know if this is what has caused the problems, or if it's something unrelated, or if they will even last that long!

Tough times indeed :(

I appreciate everyone's advice, and if anyone has any more to give i'm all ears :)

Cheers
 
they look overwatered to me, perhaps flush from now on.... no more nutes, flush with black strap molasses 1 tablespoon to a gallon and ph if neccessary to get it around 6.5...molasses will bring down the ph a little

By flushing, do you mean like water them with like 3 times the pot size of water, and discard all the excess that drains out?

Just if so, i'm not sure if that's really possible, i live in a shared house and wouldn't be able to risk taking them all the way to the bathroom and outside is a definite no as it's overlooked by many other houses, and obviously there would be no where else to drain the excess water to :(

The shit thing about the over watering is, i know your supposed to water untill the water slightly drips out of the bottom, but for some reason up until the watering today (where this didn't happen) the water would literally run straight through the pot into the tray and then we'd have to wait for it to soak up then water some more, which made it very difficult to judge how much watering they need. This may have been because they were allowed to get so dried out that at first the water just ran straight through the soil or something..
 
let em dry out completely then try do a flush, you need to get some run off into a bucket or something and toss it out....also dont let your plant suck back up the excess run offs afer waterings becasuse its sucking up all the excess salts as well which you dont want... try toss out all that run off every time . when its dry and aerated the water will usually run through nicely, it may be a little water logged now holding moisture so maybe try go 4 days without water then do that mild flush and enough space between the tops of the plant and the light...when they are stressed from anything they suffer more easily under the light making things worse

Sounds like some good advice man, much appreciated :)

I'll wait till they are nice and dry, then try and flush with plain pH (where do i get those molasse things from btw? I always though you flushed with just plain pH balanced water but you do seem to know your stuff lol) I just hope they last that long

Cheers
 
black strap molasses you should be able to get from one of those health stores, some of the guys swear that feeding your plants that stuff during flowering helps pack on the bud development...i have been using it from start to finish and my plants seem to really like it.when i flush i add the molasses again letting all the run off flow into a bucket and then i toss it out.... remember in soil if you can test the run off and it is around 6.5 then that is just about perfect for soil...

i am busy nursing a plant which i overdosed with nitrogen feeding and not i got the darn canoe like claw shaped leaves but after flushing with the black strap molasses she seems happy again, still got the claw shaped leaves on a pair of the larger fan leaves but new growth is normal and happy...

uou said you are 6 weeks into flowering so about 2 left then, this is when i start flushing mine anyway to get out all the salts and excess nutes and yes i use the molasses in those final flushes hahaha

goog luck man, you almost there i am sure you will be fine....

Yea, 2 weeks left of flowering, but last time they did take longer than 10 weeks in totally, anything from 10-12 i think is likely, but hopefully ready after ten.

Cheers for all your help man, hopefully it will all go well :)
 
Thought i'd give a quick update:

I have just spent the past 2 hours flushing the big one. I started out with pH balanced water, checked the pH and it was the same, so i then had to use water straight out the tap, which has a pH of 7.whatever my pH tester scale goes to, very dark blue basically.

So i was pouring through litre after litre of this stuff going in pH dark blue, coming out pH light yellow.

After about 25 litres of water, i managed to get the pH up to about 6.4 which i know isn't ideal, but i'm hoping it will be ok, because i couldn't continue, it was getting too dodgy, nearly got discovered by one of my housemates.

I didn't manage to get time to buy any molasses and she was getting pretty dry.

We shall see.
 
6.4 is an almost perfect range for soil, leave them for a couple of days now to dry up.....they will probably look a little droopy from the flush but thats nomal, usually after a 2 days of light they will be perking up again....next time you feed use the tap water and give a very small dose of your flowering nutes like 1ml/per litre with a ph of around 6.9 even 7.0 when you water it will lower the ph due to some of the salts still in the soil....in your last week flush flush flush to get as much of those salts out and yeah use some black strap molasses if you can as it is a source of calcium, magnesium, potassium, and iron without the salts and shit
