I’ve been growing purple lemonade autos in a grow tent for about 3 weeks. The plants are continuing to grow at a good rate, but we are noticing spots on the plants that show nutrient deficiency (specifically calcium). I’ve been using well water that comes out of the sink at 7.8 ph and then using ph down as well as air stones. I top dressed one week ago (50/50 4-4-4 and 2-8-4 at 1/4 recommended amount as well as worm castings) and also gave a tea 5 days ago (kelp meal, molasses, alfalfa, worm castings) to try to correct the deficiencies. Any help/knowledge about how we can deal with deficiencies is appreciated.
