HHHMM will have to have a look into that, sounds good though, have you done it yet
And would i continue to do that with a 12 week flower
I did it at the end of my last grow, and am doing it in my current grow at 45 days into flower.
You could continue to do it with a 12 week flower, just space it out a bit.
All you're really doing is replicating what happens naturally, days getting shorter, tells plants to put out, or get out!
