Deluxe Slurbet

deluxe slurbet are frosting up nicely and drinking about 2-2.3L of water every 2-2.5 days. The GSC are drinking 1/2 that amount and are showing major signs of what I assume to be cal/mag deficiency. I dished out a lot of cash to go with a more “organic” calcium source with Herculean Harvest (1/2 cost was shipping to Canada) but it doesn’t seem to be cutting it. Maybe the issue is Mg. Maybe it’s a disease … as these gsc always seem to have issues.. not sure Fed both cultivars cal mag at day 33
