Help! 4Week old plants yellowing/ maybe wilting

I just started fertilizing 2 days ago, 3 of my smaller plants have the bottom leaves turning yellow and I have no idea why. All the plants are about the same age about 4weeks old from seed.
My PH level after adding fertlizer is 6.8, I have NO bugs in the room. Any help would be apprecated.

Also in the grow room they looked ok but looking at the pics my big guys seem to be wilting very little. Anyone have any ideas or am I being paranoid?

since you pH sounds still fine i guess you overdone it with the fertilizer, especially since it is their first load.

i say, flush them out and let them recover from that a few days before feeding them once more. and then only with a fraction of the strangest you used last time! then you should be fine

I used 1/4 strength for them all and just the guys in the square pots are turning yellow...
What about the wilting ones? Are they ok or do you think its a cause of the fertlizer also?

I dont want to flush them because of all the problems I have seen happen to others plants here on the forums.


The temp has been a steady 85-90 when the lights on 70-75ish when they r off..

you say its just the guy in the square pot, well if that plant happens to be a dude scew it

no more fun on this, if this one is in a different pot then the rest, does this pot got the same soil mix and what is with the volume and drainage of it? volume in terms of that it is the same as tne others.
drainage because if this pot shows tendency to store water more then the others you may got a case of root rot here. with pots i keep always the same rule like with reloading ammo, everything has to come from the same batch/ no mix allowable! that can blow up you gun/ grow!

Everything is the same, I have about 6 of the square pots, 3 of them have the yellow leaves. Same soil (Farm farm ocean/perlite) same watering same everything.
I been keeping eveything the same so if I have issues I can try to narrow it down to something..

Anyone else got an idea? =/

memaw to save yourself some time go ahead and hit up the next watering with pure water and see if watering down the nutes helps them cope.

Not a definite answer but it cant hurt to try. I dont think you will lose them they might just be in awe of the nutes lol.

I watered last night with pure water and the big guys perked right up in 30mins!
The square pot guys are still yellow at the bottom leaves we will see tonight how they r doing.
Thanks Godkas
