Seems like the ppfd experiment got derailed by other things. What I initially thought was light damage only got worse as I dimmed the lights. A day or two later and the leaf symptoms started to look eerily similar to the one and only time I tried to use RO water. Calcium deficiency at this stage of growth?? Wtf. 3/4 of them were experiencing the issues much worse than the 4th.
-put new tap water in my pump bottle
-top dressed the girls with 1 teaspoon each of Gypsum, Epsom Salts, and the Rock Dust Blend.
New growth coming in nice and green. These plants are gonna make me go bald
