Well, the 6/9 wasn't working as good as the MB did on my first coco run. Through week 4 the bud development stalled and was nowhere near advanced as the same strains on MB. So I reread H3ads and Rezs threads to decide what to do. I found a post by slowandeasy who used blumats like I do. He used the KB not as single blasts but in weeks 4,5,6 he mixed the KB into his rez at 1/4tsp/gal with 6/9 and fed that daily thru blumats. So that's what I tried, the ec was still 1.2. The buds exploded and within 3 days are further advanced than on straight MB at the same stage. So that's where I'm at, no burn and healthy plants in week 5 and if it stays that way I'll run the low strength KB through week 6.
KB is kool bloom? Liquid or dry? And just so I understand...youre giving them 6/9 at 1.2 with quarter tsp koolbloom on top of that? Are you gonna drop it totally after week 6? Also whats blumats?
