Well, I'm on week 4 of flower on my bubble bucket scrog grow, and I have hit maximum ppm right on schedule. I am finally burning the leaf tips, at 1800 ppm, which equals a whopping 3.6 ec. I'll call it 3.5 even tho I use RO water.
I'm growing 3 northern lights hybred crosses designed for low odor apt. growing.
I had one indy dom plant but it died long ago from the strong nute solution. I was wondering when I should start lowering the humidity? Is it week 6?

I am using advanced nutes 2+ formula, but my buds are kinda smallish looking to me. When will the big bud make the buds get big?
