First grow.Blackwater w/ H16/HLG LED

First grow, first diary. Got 3 Blackwater clones in mid-April, and started 4 bag seed 4 bagseed in 2x4x5ft tent with HLG 260W XL LED, in 3 gallon smartpots. 3 Blackwater in 2x4x6 tent with HLG 320W LED, in 7 gallon smartpots. Bagseed had wind damage on some plants, and are not yet showing sex. One of the Blackwater clones I bought had spider mites in early May, and I treated with Wipeout. I let the inline fan turn off for a few days during dark period in veg. That introduced powdery mildew on one leaf on the same Blackwater plant. Removed the leaf and treated the whole garden to a spray from local shop. After discontinuing mite/PM sprays. Started spraying with Heavy 16 foliar, and using Heavy 16 lineup all throughout veg, and in to flower. Everything is planted in Roots Organic soil. I have had struggles delivering the right levels of nutrients, and have heavily diluted the solutions as a result, and often feeding plain water. Some leaves have shown nutes burn on the Blackwater plants. On top of that, I have over watered plants at times, and they have appeared droopy. Overall I find it a bit difficult to get right, there is definitely a huge learning curve.
