I know its a discussed topic non stop. Some people argue to death led doesnt cause the need for more mag. I also feel calmag is such a boy who cried wolf scenario. Cal/mag has been screamed so many times nobody would actually believe they had a calcium or magnesium problem if that was indeed the problem. I have ran tests and it is 1000% IMO and IME that Led dialed rooms need a lot of magnesium, strain specific. Here is a peanut butter breath the older growth is showing some deficiencies. I gave 0 magnesium supplement this first week after transplant and turned lights up to 400ppfd. The plant in 2 days had interveinal chlorosis within 5 days it turned necrotic. I then foliared magnesium and root drenched magnesium with my nutrient schedule and viola the new growth is lush and healthy. I should mention my soil slurry is right on point at 6.6ph 500ppm 1 day after a 1800ppm organic bottle feed at 6.4ph. My starting water is 140ppm 7.2ph. I added 7.5ml of mag amped/gallon in each feed these last few days. Hlg 600r 36” from canopy. Ppfd was raised from 300-400 over a weeks time. The older leaves were healthy before the light increase, you can see the middle of the damaged leaves are a nice green with a healthy vein.
Old growth pre mag supplements soon as I increased ppfd:
Few days after supplementing magnesium.
