Nutrient Issue - PICS INCLUDED!! HD

thanks for stopping by to help

so im in week 10 of veg... these are mother plants i just took clones from and i thought it was a cal-mag issue so i just fed them a quarter of a (maybe a bit less) gallon with 4ml of cal-mag yesterday. i PHed it at 6.7 going in but i didn't record the runoff, there was a good amount of it. my question is what deficiency does this look like to you guys and how long does a cal mag issue take to stop showing signs?

the leaf tips have been turning brown/tan/grey and curling up and becoming crispy dead

i think it may be a bit too hot when it comes to the N cause im noticing the leaf curl down at the top of the plant

I'm not very good with nutrient deficiencies, but it really looks to me like a lack of Nitrogen.. Which is weird because of the "claw" which is usually N tox. Cal and mag are two different micro nutrients, so if would be better to add one or the other if it's a calcium or magnesium deficency, but mag def. usually start at the bottom of the plant and the tops of your plants look the same, the plant looks as it's experiecing lock out of some sort due to pH would be my guess. Measure the run off pH if you can, or make a slurry and test the slurry (since you just watered I wouldn't suggest watering to get a run off for a while), a slurry would be the better option. Hope this helps.

For me the clue is 10 weeks in veg,,,

I'd be checkin the roots and prolly upcan it

Sometimes root bound issues can cause weird stuff to happen but with that said, I have some plants in 2.5 gallon pots that are healthy and have been in the same pot since april. But I have had plants that look crappy, then I repot and all is fixed. I think it could be a salt build up causing issues, or just the ph over the course of time became out of whack

so give the roots a little manicure? im trying to keep them small just so i can take clones off of her once every few months, and if i put it in a bigger pot surely its going to get much bigger

remember these are only mothers... they are never getting flowered. and they are getting moved out of the tent and into a muchhh small space so size is most important besides health

-----------

i'll deff be checkin the runoff ph for the next water... i haven't been checking it tho cause i got flamed wicked hard by someone on here that told me runoff ph is worthless? i thought it was important but w/e since then i stopped checking it; i'll start doing the check again tho

ya im aware they are separate. but considering i just bought a new bottle of cal-mag plus not really worth fretting about. i've grown out a dwc of WW and never had a problem with mag or cal becoming unbalanced from one another and im using RO water so im sure it can use it and on that grow i got well over 1 gram per watt

but ya the N issues has got me baffled, which is why i think its something im not thinking of or just a ph problem, but idk how that could be since i've been pretty constant with ph and it just started being a problem, which is why im thinking it may just be a nutrient that i just gave it but hasn't fully been sucked up and used by the plant yet? idk

i think it might even be a mirco nutrient deficiency but because no pictures i see are doing what this plant is showing me idk, its annoying. i wish there was more picture references online... but every time i search its like the same bullshit that comes up... just too much shit to sort through to get a straight answer... its not like i haven' tried hard. even the guide on this site is wicked broken and missing many pictures

Right on, I'm a hydro guy myself and seem to have more problems with soil, but learning to get a little better with soil grows. It's way harder IMO to grow in soil, at least for me anyway. I think the soil runoff isn't pointless. Are you organic? I don't think ph matters as much with organics, but i think it does for non-organic mixes. I keep my mother plants in the 2.5 gallon containers for a year with not too many issues so I think you can fix the problem with out repotting, just my opinion though.

ya i deff agree... soil is a utter pain in the ass

DWC is my thing... i like to scrog. 2 plants under a 400 watt and i can easily get over a lb

----------

im using like year plus old organic 'natural' nutes from humbolt

the natural grow, natural bloom, and equilibrium. and i jsut bought a fresh bottle of natural Duece Duece which is a Potassium Supplement supplement

----------

for my DWC i use the lucus method using general hydroponics nutes... mirco and bloom only with cal mag as needed

For sure man! That's awesome, I love 2 plant scrogs, thats a damn good yield off from a 400w, incredible man. I'm pretty new to scrogging but it's awesome what it can accomplish for yields. I even use the scrog net when I'm not scrogging now, it's perfect for bud support. Last grow I did a 6 plant scrog and it came out ok, my current grow I did 11 plants in a 5x5 space and topped each plant for 10 tops, so it turned into a low plant number sog but with soooo many tops. Worked out great

Oh, I use dwc and ebb n grow buckets

also im thinking this could be a K toxicity cause i read that causes a cal-mag lock out cause i just fed them 0-0-22 of duece duece with 5ml in a gallon about a week or so ago maybe not even

so is this a case of ten weeks of veg and no food? i read that you added calmag a bit but theres no mention of food? are you feeding yet?

lemme see if i can upload my feeding table on excel... too much data to write out... but in short i didn't start feeding them untill after week 6 when FoxFarm: ocean forest soil lost its nutes





plant #1 is the plant i posted pictures of... plant #3 isn't shown because it looks lush green

ok so the plant im having a problem with finally needed to be watered today so now i know the runoff is 5.97...deff too low to optimal.

so now that i know i need to flush that plant... what is the BEST ph level to use? i have some spring water that is at 7.01 ph and some RO water that is 6.7... should i consider using 7.5 or even 8.0 ph to raise the soil's ph? i don't wanna over flush her but i don't wanna raise the ph by only .2 i really am looking to raise it atleast a whole .5 above where it is.

anyone with experience with flushing and knowing how much of a PH change in the flush water im going to need to bring my plant from a 5.87 to atleast a 6.5?

thanks in advance for helping!

#bump.... any help?

What kind of soil is it again? I think you want the soil to be around 6.5, so if the run off is 6, try using the 7ph water, that would be my guess :/ but wait for someone else to chime in.

its fox farm ocean forest

Ok, I think 6.5 is where you want to be in ff soil so I'm guessing you are getting some lock outs due to the low ph. I would go with the higher ph water and get some good runoff and test the run off again.

lol yep, i just really need someone who has already done this before so i can know for sure how much higher of a ph i should water with... i know it should be higher but HOW much higher is my question

thanks for trying but legit i've searched all these pics before on my own on google and various other grow blogs and i still have no idea the answer to my question... because i don't want to OVER raise the ph or not raise it enough

---------

im just gunna wait a few hours to flush it until i get a more accurate idea on what i need ph level wise

right on man, I'm sure someone that has been there and done it will help out, I wish I could help ya more, I have been in the same boat as you and never figured it out lol. Soil ph is a pain in the ass once it gets messed up, I know that dolamite lime will help stableize the ph better, so possibly next time you use soils, mix some lime in there to "buffer" the soil, it might help but who knows, so many unknowns going on in soil lol
