Yes, this could have been a GREAT harvest if they werent so airy.
I did do a 1 day flush every few weeks throughout. I think my problem was with heat. I had it @ 85 beginning of flower ( I thought this was OK with CO2) This was way to hot for them and they started to stretch. I thought dropping the lights lower would stop stretch, this just made things much worse. On top of that they were very sensitive to nute strength, so PPMs were only around 500-700 ppm most the grow. And at the very end I got a MAJOR case of root rot, which probably would not have happened if they were not so heat stressed.
Next run will be all 4 lights Blue Dream. Will keep it cooler, and keep the lights higher until later in flower. Will also be using potasium silicate through out veg to strengthen and make them more heat tolerant. Wish me luck. Next round should start tomorrow. WHAT A BUSY WEEKEND! haha
