Anybody seeing Mg deficiencies with the usual 2-2-1 masterblend ratio, in coco under Samsung Lm301 LEDs? 2-2-2 in 140ppm tap water seems to be the better ratio under high powered LEDs. At least, that's what eyes are seeing round these parts.. the 2-2-1 works great for veggies under those same LEDs though.
