100 gallEpsom salts. Takes care of magnesium and sulfur. How big is your rez?
Mg is intervenial chlorosis, not spotting usually. I think it looks more like calcium deficiency.I would lean toward the magnesium more, but your girl looks great.
I do 8 grams per 12 gallons,hot water, mix separately, then add.100 gall
new growth under light , yeah looks like calcium , i use entire H&G line with no calmag cuz their support said aqua has a lot of calmagMg is intervenial chlorosis, not spotting usually. I think it looks more like calcium deficiency.
Is it mostly on the new growth/ leafs with lots of light, or is it mostly on the older, low growth?
thats what i didEpson salts won't help at all in the case of calcium deficiency
Personally I just up the PH a few points, and up my calmag
Its rare to find a toxicity with calcium and magnesium, so I wouldn't really worry about going too far with that.
I run 250 ppm (500x) of just COCO cal (pretty much calmag) then I add my two part base ontop of that.
also do you know correct ph range for max calcium uptake ? some charts say 5.8 some say 6.1Epson salts won't help at all in the case of calcium deficiency

Interesting that mag is lockout at 5.7-5.8 support recommended me to keep PH at 5.7 , and my ph drifted to 5.5-5.4 couple timesI think this chart is very comprehensive and shows well where nutrients get uptook best View attachment 4816228
These are optimal levels is all, of course you need to be in the white with some nutrients sometimes, esspecially when you want to uptake another nute in particular. Just try not to go in the redInteresting that mag is lockout at 5.7-5.8 support recommended me to keep PH at 5.7 , and my ph drifted to 5.5-5.4 couple times
I think i went to red couple ofctimes thats what happening to leaves. Also i have 2 bluelab ph meters and both showing different reading right after calibration. So its garbageThese are optimal levels is all, of course you need to be in the white with some nutrients sometimes, esspecially when you want to uptake another nute in particular.
