I wonder if nutrient lock out is what is ailing my baby plants. I have some nasty necrosis on my lower leaves, though I am using coots mix living soil... so I dunno if maybe I just added way too much amendments when I re-amended the soil and now it has way too high a content of something, or if there is a way to even combat that with living soil. I was always under the impression the microherd fed the plant what it wanted and so burning and excesses were a non issue (deficiencies a different story).
I do seem to recall during my first grow with photoperiod plants that I did end up getting some cal/mag to give them for some leaves looking like OP's and it may have helped. But I also just started PHing my water again too. Everyone says it shouldn't matter with living soil, and I am pretty sure my water isn't very alkaline so it should adjust/drift to the substrate vs causing the substrate to drift. I probably should get one of those soil PH meters if they indeed do work pretty well.
Also may be worth trying to take a soil sample from 6 inches down into the pot and send it off to truly see what I am working with otherwise I feel like it could be just guess work for someone on here.
