Auto HST test AvT / RQS Diesel Auto

((EDIT: hopefully fixed pics. I just cropped the pictures of each pair, not feeling like pulling them out for individual white light photos tonight)) Flowering progressing well. Couple of youngest still not really going, they're going to be a pain when everything else is harvested and I need the cob tent. 12ML daily isn't *full* 'light feed' strength but I'm feeding it daily which is almost certain overkill. Any attempts to cut back have only met with iron def -- even with 4-5ml calimagic -- don't even know what to do. I guess i should get my tds/ec meter out and start testing the tap for the Canna calculator. The numbers it spits out are for every other day I think though? Got more rhizo. Gave all three tents 8ml first night, 4ml second night.. from now on prolly 8 for seedling 4 for veg 2 for flower. Thoughts? EDIT: Whatever's making the back ones waxy and curled, I'm not sure -- none of the green crack I grew in coco had this issue. Any of the pH spots I have I believe to be from just not being patient with my crappy pen when I do my balancing, as I have to do extensive balancing for the silica for all three tents. These ones are a bit pickier I think. I didn't have these problems with this method with the seedsman critical mass or the fastbuds green crack, and I know some strains are more sensitive.
