Thank you so much for your feedback, it could be the led making the leaves a little blueish.10.5 ml a gal a/b and 5 ml cal mag is way high. I run hg nutes and co2 and I only use 5-6ml gal a/b, 1ml cal mag, and 2ml tps bloom for my p k boost. Hg are my favorite nutes but I think they’re a bit lacking phosphorus. Looks like your plants are a bit lacking in p too, that kinda blueish green color of the leaves. Too much cal can lock out phos. Try knocking your nutes down to my levels. It will probably take 2 weeks or so to see an improvement.
thank you, they are also in coco, maybe just lower calmg and a/b a lil bit?Agree ^^^
but the rust spots are calcium deficiency locking out from too much nutes. Full dose of cal mag rarely if ever needed.
Maybe run some fresh water through to leach out some excess and re feed a lower strength without all the additives.
plants look good. Nice work!
