Yea after looking at the Earth Juice bottles I have (Grow, Bloom, Catalyst, Microblast) I notice that they lack a few nutes such as sulfur, calcium, chlorine, copper, selenium, and silicon. I dont know if this is part of my problem. I use 1/2 tsp of superthrive but I dont give that to them every time I feed them. I only use RO water because my tap water leaves the crusty white ring around the top of the soil level. I was debating between Fox Farm and Botanicare nutes for next grow. I read the labels on their websites and it seems like FF has more nutes but Im no expert. O yea the heater is about 8ft away from my veg cab. You guys rule!!!!!!!!! :jointsmile:
