Yeah none of that seems to be helping ive researched for a long time before I posted on here, the closest thing I saw was boron deficiency. I upped the PPM up to 900 a few days ago and now its at 750, AND almost all the water is out of the reservoir! I stopped using the MagiCal too so I don't have the tons of Cal.
Im using Magpro instead, and I see improvement with the curling and spotting seems to have stopped, I do see slight yellowing / lighter green areas, could be its just trying to recover, I think I was severely underfeeding for a 3 month old plant, and I was probably causing some sort of lockout with the tons of Cal.. I read Cal is a Boron antagonist, saw it from looking at Mulder's Chart. and it was way out of the recommended proportions for Potassium Cal Mag..
It is NOT light burn, NOT heat, NOT bugs (I've checked many many times), unless anyone has any other ideas I'll keep you updated on my quest for a fix!
Also it is very doubtfully a Cal or MG deficiency, Ive fixed a MG def it had by using the MagiCal a long time ago, and Ive never seen it have further problems till after the MagiCal, although slowly, it was getting worse and worse and Ive thought it was nute burn, fungus, all sorts of things.. Im not trying to sound like a know it all or something but these are just simple observations and if im the wrong track let me know! (remember I said I made a new nute solution with a lot more nutes, no MagiCal, and its only a few days later and they drank almost all the water, in addition to the PPM down to 750 from 900! Also i havent seen new spots!)
