[SICK][PICTURES] Yellowing and curling down. Young plants [PICTURES][SICK]

Diagnosis please? Anyone?
Short list of things i think it could be:
Nitrogen deficiency
Under watering
heat stress.









any help would be appreciated.
Hurray for thumbnails =/


 
Around 4 weeks old. Just started with some organic nutes, very diluted every 3 waterings. It cannot be over watering because have been very precise and waiting for them to dry out completely (soil) before giving them another drink.

Cause you deff got a lockout from ph issues or a salt build up try a good flush but i need to know your ph before you do this
 
Tap water, and Will test ph shortly. I think it has sufficient light. So it's looking like the ph of the soil is the culprit. Would re planting into fresh soil be too much of a shock for the plants?
 
Lock out you say. Thanks for the awesomely quick replies everyone. Looking for the ph strips now, I think i'll move them into new pots anyway, so new soil is looking like the way to go.

Everybody says it does but from my experiece do it carfully and no difference at all and wouldnt hurt to go to a bigger pot too it could also be a root bound issue i forgot that one how are the roots ??
 
Roots are visible in some places through plastic, but are not curling or turning (with the cup) yet. barely out the bottom either.
Repotting and checking ph now. Will update when I get back. Thanks a lot 0calli.
Sorry for the double posts.

How is the drainage in that cup, also you might need more room already, so get it out of the cup, it also might just be a crappy seed...looks a bit barky in that cup too, so I would transplant honestly i vote Foxfarm Ocean Forest, at this age it's perfect and easy, just add a little perlite and then water it...lol. but not too much
 
Just realised, it's not tap water, but untreated rain water in our home tank. Also, the cups have good drainage, many holes in the bottom of the cup.

i hesitate to say this because i know there are anti-lime nazis out there, but if that were my plant i would water it with a liquid lime solution or top dress with some finely powdered dolomite, wait a week, and check for healthy new growth.

i'm sure it would like a new pot as well, but IN MY OPINION if you don't correct the problem in the cup you'll never get a handle on it in the new pot. i plan on making a tutorial on this soon but i need a few more example pics and fucking up a plant just to make a tutorial isn't in the cards right now :eyesmoke:

liquid lime at 1 tablespoon per gallon OR a top dress of FINELY powdered dolomite and plain water. do not use agricultural lime or any other lime that is in chunks. understand it will take a week or so to do its thing, but your focus right now should be on GETTING HEALTHY NEW GROWTH.

if something is up with your soil or stock water, repotting is only going to delay the problem, not solve it. since the plant is stunted anyway, you are not "losing out" on growth time.

flame away, lime nazis.
