Seedlings not doing so well....add GH nutes?

[headshake]

My seedlings arent doing so well in thier humidity dome, some are straggling and the others are doing well but have some yellowing of the leaves. I think I put a few too drops of superthrive after reading seedlings get one drop per gallon. I flushed them and put them under cfls instead of my 90 watt UFO. Now reading my GH 3 part flora nutes, its says seedlings and cuttings get nutes @ 1/4 tsp / gallon. I thought it was only distilled water and a drop of superthrive for the 1st two weeks?? Should I add nutes now or wait? Temps are 84-93 and humidity is 90%

Heres a few pics, they are 7 days today from putting in a paper towel

looks like you could be experiencing heat stress. you need to work on your cooling/ventilation. the 84F is acceptable but beyond 90F might be a bit much for seedlings. these aren't established plants but delicate seedlings.

they don't require high humidity as they are seedlings and not clones. the humidity dome is used in cloning because when you take a cut, that cut transpires out all it's water without having roots to replace it. this is why clones wilt. this is also why you've (more than likely) seen clones with half of the leaf tips cut off.

so take the dome off and get the temps in check before deciding to feed any nutes.
