Month old seedlings in dwc yellow color and brown/copper spots- nutrient deficiency?

[moash]

anything i can do about the rocks now?

well,when u change ur rez,u can run water through(use ph'ed water since there r roots involved)
or continue to change ur rez til it stops risng
or get a bucket and take the individual pots and dunk them,but make sure to keep ur hand over the top so the rocks dont float out
