I have 2 plants in their own DWC. They have always been fed very lightly on the .7 scale @ 300-400 ppms. Were green and happy, no ugly leaves. Now After flipping to 12/12 I've come across a deficiency that seems to be pointing to iron. Well I foliar fed a small amount of calmag and bumped up the ppms.
Which leads to my next post of pictures from day 24 from flip.
