100%...I tried to keep 6 in my flower tray and harvest 3 every month, but like you, I ended up adding some longer-flowering strains, phased out others I knew like the back of my hand, and voila! unpredictability led to poor results. I also got 33g from one of my indicas that in previous runs had given me 3-4oz. My fault. I let soil energy get low, I didn't veg long enough and the plant simply wasn't ready but still, I can't subsidize that kind of thing right now. So, back to basics with fresh soil, longer veg times, lighting upgrade...it won't last long. My flower tray is something to behold right now already and they still have a good 4-5 weeks to go.
