Ace's no Zushi! 100% organic

So, today is the 28th day, both the bubba and kmintz were topped, the first is finally growing the secondary shoots, kmintz was topped two days ago so still nothing, from this moment on I'm not giving them any more root stimulators until preflowering. This time they're vegging slowly, but I cant get what I'm doing wrong. No problem by the way, I'll just let them veg longer
