looks like it get some at the roots and foliar feed some and raise your light up a foot. Led is washing out the mag in the top section.

Thank you for the reply, what should I use to foliar feed and how do I make the solution to spray them with? PH, ec etc..

epsom salt no perfumes no dyes 1 tsp per gal put some in a quart sprayer or whatever you have, add a little surfactant / dish soap clean soap/natural soap......use the rest at the roots do the spray for a few days do the roots once a week then re-evaluate, is more foliar needed etc. then do it every few days with the foliar. etc.

dont need to ph the foliar unless you want to, add some microbes to the soil, no need to ph microbes take care of that at the root surface
