Grow mates, At F 18, I am happy with the speed of flower development. Mac's especially are crowning nicely. I wouldn't expect to see pistils like this until week 3 so slightly ahead of the curve here. They are looking nice and straight also so watering on point. Bodes well for good bud development. Upped my feeding after checking run off which was only 350ppm. A surprise. Better than over feeding though. Seeing the first signs of frost on the Mac's. The garden wafts of Mac cookie smell which is quite beguiling. Lowered ph to 5.7. Leaf claw is diminishing. Feeding at the water stage of the cycle. Ph'd water and Elite 91 Flower only which works out to be about 400ppm when administering at 2ml. per gal. Strong stuff. The stretch is not over yet. Hopefully over soon. I prefer to keep the lights 24" from canopy. Lower canopy at 500 micro moles. upper canopy 800 - 1000. Most if not all canopy will be fully ripe 7 weeks from now.
Happy growing all.
