Hello, I have some Alaskan Ice clones in Hempy Buckets, approximately 2 weeks in veg showing magnesium deficiency on some of the older leaves. The clones are showing decent growth, and the newer leaves are not showing deficiencies. I decided to add Cal-Mag to my normal feeding, which is currently General Hydroponics Flora Series, 5-5-5 (5ml per gallon of FloraGro, FloraMicro, and FloraBroom), and was curious how I should go about doing it? Do I need to cut down on other nutes when I add the Cal-Mag, and how much Cal-Mag should I add per gallon? Has anyone had any experience with using GH 3 Part along with Cal-Mag in a hempy bucket or hydro setup? Also would there be any benefit to adding Superthrive to my veg feeding? I was told by a friend that it would help with nutrient uptake and overall plant health. Is there any truth to this? Thanks in advance for any and all input
