I have had my 3, 8 week old plants under a 400w hps bulb on 12/12 for 5 days. I want to know if I can change them back to 24 hour light for a week or so to get them. Little bushier. Just don't want to shock them. Is it possible?? And how do I do it.
why not just let it stay in12/12 and do a little training to make it bushier? I think switching the light back would be pointless.
since you already flipped these girls Ide say just do some LSTing. How To LST(Low stress training) Click that link for all you need to know about LSTraining.
Re-vegging is enough stress to bring out herms in some varieties, plus some say the quality can take a dive. The posters above me are 100% right. Stick through with and make the most of your current grow.
They won't lose potency until after a few re-vegs. At least through my experience they didn't. So this round I'd snip some clones.
