bah well you just fed them with bloom nutes(low nitrogen), and you fed them with cal/mag(competes with N for binding spots on the roots). so yeah your leaves are gonna get worse until they get a balanced diet... or at least some nitrogen.
so in the mean time instead of letting all your solar panels die,... get a spray bottle that can mist, and fill her up with diluted veg nutes. what is your veg nutes npk ratio, that will help evaluate how much you can use. also only spray your leaves when the lights are off, or else they will burn the leaves further.
