Im a frequent bushmaster user and love the shit. It looks like you may have run it for too long, thats where the excessive leaf curl comes in. Bushmaster containts a VGI(vertical growth inhibitor) that WILL stop vertical growth, decrease node spacing(to the point of super rock hard colas), as well as greatly increase the speed of transition to bloom.


What i do is run in through my recirculating system for 4-5 days at half strength(i cant remember what the bottle says exactly but i just cut it in half). I do this the first week of flowering, the day i switch to 12/12. At day 4 or five I start to notice the pretty good leaf curl starting on the newest colas, then I dump the res and get rid of the BM. This seems like the sweet spot for me, you just have to experiment.Attachment 273849
