I take a lot of this advice with a grain of salt...this weed is tough and wants to live. Do a lot of reading. Learn, learn, learn.
My last grow, I only vegged the clones for 2 weeks before flip.
Diamond OG and Corleone kush both grew as expected...stayed pretty small and produced about an ounce each. I was going for a fast grow, yield wasn't much of an issue.
Kimbo kush's, same veg time...both got over 3' tall and about 3 oz per. God knows what they'd have done with a proper veg. We'll find out this time around..
Much of what you do in your grow will be tailored to your space, lights, temps, grow style, strains....so many variables that impact the final outcome....
I do many things "wrong"....but I love growing, and what I do works for me. It took two grows to get a handle on this new setup and new environment..(I moved to the desert).
Everything is now dialed in and this third grow should be the real deal.
Hang in there...it gets better...
