Cm.....I'm glad you asked me that question. I WOULD take them up to 1200 if I were you but then what I'd like to have you start doing .......starting around week 3 of flower is to start backing off VERY SLOWLY on your Cal Mag. You want to keep them on a 50/50 mix through the second week of flower while they do there big burst thing.....probably what you are seeing right now. Then they start slowing down on the height and making buds. This is when we will want to ease back on the CalMag and introduce more of the Pro Bloom. By week five we'd like a 65/35 ratio of probloom/CalMag. .....topping out at 1200 (perhaps more if they continue to eat like such pigs but we'll wait and see) until the eighth week or so and then flush. If they need to go longer they can just go off ph'd r/o water until they are finished.

Capice?
