First try at hydro: FBTO1

Real flowering started this week. The stretch just started and the crazy bushiness continues. Did some fairly heavy defoliation on the under canopy and select large leaves blocking light to the bud sights.... but controlling the growth is a balance. Trying to keep as much photosynthesis as possible until I can really tell which bud sites will be the real colas. I did a full reservoir swap with flowering nutrients, and a pH balanced water only flush in between (about 18 hours just running pH 5.9 water). Once I put the new nutrient solution in, the plant just shot up. It was spectacular the difference in literally only half a day. I have noticed that a thin coating of something was on the air line of the bubbler and a couple other surfaces. Cleaned it off before the water flush, but still note a very slight film on the top of the fresh nutrient solution. It's a touch worrying but not sure it's an issue. Will watch carefully.
