What’s up DGC. I need some help with my girls please. The tops are starting to yellow out and some are dying. I thought it was a magnesium deficiency but I’m not to sure now. I’m using dr. Earth dry amendments. Which have an npk of 3-9-4 also using compost teas once a week with some worm castings and the dr. Earth nutes. I’m in a 2×4 tent with a mars hydro sp250, my temps are around 79f to 82f with the lights on and off around 74f. Humility ranges from 45 to 55%. I should add that I feed her a gallon of water with one teaspoon of epsom salt in it. I pH adjust my water to the range of 6.5 to 6.8, as my well water is 8.1. I use lemon juice to drop my pH. I’m not sure what I’m doing can y’all please help me out.
