Day 17 update
The last feeding was the strongest and almost had the perfect ratio of nutes/water. The girls only ate about 30ppm for a week straight. I added just back plain water to the system and is currently at 280ppm. I finished cleaning up the underside of the canopy last night and got a small fan blowing to get the air circulating more. Temps have been sitting at 78F during the day and 63F at night. I am really hoping to get some purple color this time around. I may drop a few more degrees, but ill wait a few more weeks before that happens. The stalks on these girls is absolutely outrageous. Keeping that ppm low has really made a difference.
