water level to high.
PH to high.
Nutes WAY to high.


water level should be about 1" below netcup/basket.
PH should not go above 6.0 but no lower than 5.3ish
Nutes ...... if your using the same as me (floramicro and floragro, you listed as Floro), then your way to high for lil ones like that. ST is a great add but nutes no more than half strength until you have like 3 to 4 sets of true leaves. No nutes until atleast the 1st set or true leaves. Watch the temp inside grow area, have good air circulation and drop that light about 2 foot.
post some pics if you can that way we know where these plants are in life :thumbsup:
