Oops- might have messed up and have wrong lighting???

Rush2112started grow question 4 years ago

I might have confused the two strains I’m growing and have been treating a photo period as if it was an auto (18/6). In week 5 lots of preflower but no real top buds formed yet, I’m wondering if I screwed up with too much light. Should I switch to 12/12? Will 18/6 hurt a photo

Hi there! Hmmmm.. I think you are mistaken now and everything is like it should be. If you are giving 18hours of light and 6 hours of darkness and the plant is pre-flowering then it most definitely is an autoflower strain. Photoperiodic cannabis will start to flower only when there is 12 hours or more uninterrupted darkness. When you want to flip an photo in to the flowering you change the lights to 12/12 and only after this the transformation begins. So 18(lights on)/6(lights off) will not hurt your photo but is actually considered optimal light schedule for vegetation!! 👌

Thanks Shagrath. I do have some photo periods that are also showing pistils in the nodes but surely they have not been in absolute darkness for 12 hours in their 5 week lifetime so how is it they are preflowering? How do strains that are grown outdoors switch to flower without the strict 12 hour darkness phase? Thanks for the help

Weird Autos (RQS NLA, same strain) still vegging day 50. Only some preflower, but nice plants. WHAT would YOU do?!This is the most unpredictable auto flowers I've ever had. It will be 50 days soon and only preflower on one plant. Ive used a 12/12 light schedule on autos before. Should I try this on these plants? If, so keep it 12/12 untill the end? No turning back to 20/4 when they go?

If this was yours, how would you proceed?Going into week 6. I just clipped the bad leaves that show in the picture and will be switching to the growing stage. I plan to do the 36 hours of darkness first. Already changed the water and it has the bloom solution instead of the grow solution. What would you do now?

Erratic light cycles for the first week Any experience with keeping a seedling in 12/12 to begin with, then switching over to 18/6 after the first week? Because I did that this time for tech reasons, and I do wonder if I produced a hermie. My own notion is that it will just set me a week back perhaps. Anyone know tho?
