I've seen preflowers at 2 weeks, it's normal. Just use them to sex the plant. I always get my males out by week 4 veg., if for no other reason than they take up precious light space.
luvtogrow Reviewed by luvtogrow on . Is Pre-flowering comming to soon? My plant is in the pre-flowering stage, but I want my plant to grow bigger before it flowers. Can I keep the lights at 18/6, let it grow for 30 more days then switch to 12/12? Or do I have to let it flower now? Rating: 5
