I have 12 mini Rockwool cubes next to the window 1/2 way up with water, air pump and heating mat at 72-76F. Humidity dome. (Day 10 from sow)

They flopped on me.. not dead but leaf to ground,

They were ok with:
3 quarts water
pH 6 citric acid
PPM 400
Potassium nitrate : ammonium phosphate
1:1
H2O2 1 ml/quart

Flopped after water change:
3 quarts water
pH 6 citric acid
PPM 650
Potassium nitrate : ammonium phosphate : calcium nitrate : magnesium sulfate
1:1:1:1
100 ml kelp tea 1:50 kelp:water brewed
1 TBSP aloe
H2O2 1 ml/quart

They look better now that I have a fan and CFL on them, added plain water to dilute to 400 PPM, turned off heat mat, took off humidity dome

now there is an arch in the stem as if they will get back up.

Anyone see the problem/ is it the nutes?
Lack of light/ no wind stress?
I feel like a noob every time I sow.
