6 weeks into flower. Chugging along. pH has been dropping like mad for a couple weeks now, I have to up it every day. It's never been this drastic before. Maybe it's because I've never had this many in the system at one time, and they're just feeding like mad thus raising the ppm and making the H20 more acidic? I've had to top it off with 5gal every 10 days or so, whereas before I could make it to each res change (every2wks) with no topping off. Anyway, they look great and handled the recent heatwave no problem. Temps in the closet got to 90 F at one point, no sweat.

Outdoor pics coming soon! They're getting huge!
