Phototron hybrid

This will be the last week. I will harvest next weekend. As the buds are looking really large and dense & the leaves are starting to curl. Running pH balanced water with 1 tablespoon of Kool bloom alternating back-and-forth without and only hydrating soil for 10 % waste. I also hear just before harvesting you’re supposed to leave it in the dark for 24 hours to make it increase sugar levels to produce more THC not really sure if that’s true! Love advice on harvest techniques, drying, wet trimming vs dry trimming, proper curing in jars.
