The Cannabis Grow Bible states in bold and enlarged print. "You will get the best out of your plant by waiting until it starts pre-flowering before switching to 12/12."

I'm waitiing for the calyx development to appear before switching to 12/12.

I was just trying to get an idea of how much longer I'd be waiting.

Last year it took the same strain 7 months to begin flowering

before 2 went hermie.

Thanks for your input!
