If someone could chime in with some knowledge. These plants are in coots mix. Two plants in each SIP. 20% compost, 40% perlite, pumice, and rice hulls. 40% peat moss. Plants transplanted from 1 gal pots to City Picker SIPs on March 2nd. Started noticing deficiency (nitrogen on some, magnesium as well, but mainly on the Gorilla zkittlez) around March 21 and top-dressed with ewc and watered in with fish hydrolysate. Have done a few foliar feeds with Epsom salts, sometimes including TM-7. On March 26 I top dressed with more coots mix medium. The one pic shows a Gorilla zkittlez from Barney's Farm that the leaves curled, and showed what I thought was magnesium deficiency, thus the foliar feeds. I had the ppfd up fairly high (around 700 ppfd), so I've backed the light off a bit. Temps have been between 82-84°F lights on, 76-78°F lights out. Humidity has been fairly high, close to 70%rh lights on, 65%rh lights out. Have lots of air movement (maybe too much) and good extraction with 4" intake, and 6" exhaust with ACI inline extractor fans. No carbon filter yet. I have ordered some calcium nitrate and was going to use it in a foliar feed hoping to balance out the calcim/magnesium as it appears on some leaves, that along with nitrogen deficiency, a calcium deficiency is appearing. Was hoping to get some confirmation on what I'm seeing, and some advice on the use of calcium nitrate in a foliar feed, as in concentration to use. Any help is appreciated.
