My guess would be a mild magnesium deficiency.
The foliar spray is probably causing your plant leaves to become weird - they don't need the foliar spray so I wouldn't do it - Foliar spraying is for applying something directly to the plant that it would need immediately. Example: my aero clones are lime green cause i used just water to root them - and they aint turning dark green anytime soon - Foliar spraying nitrogen will help them uptake it faster/use it right away - opposed to feeding N to them and making them work to get it and making the recovery process longer. In your case your babies just need to grow and foliar spraying them is probably hindering their ability to photosynthesize to their maximum potential. Also the water/light combo does silly things to plants some times.
More importantly...
Aero requires COLD water.
MAKE SURE YOUR WATER TEMPS ARE BELOW 75.
You want 70 degree water ideally. Warm water kills the plants.
Whats the type of light/watts you are using.
If its a t5 drop that shit 4 - 6 inches from the tops
A MH/HPS should be a foot away at least with a good fan/breeze.
sorry if anything is redundant - just trying to help and I didn't look into the details in the beginning of the thread.
