24 hours of dark best for what? Yes, if growing photoperiod plants you go to 12/12 to stimulate flowering. If growing auotos, stay at 18/6 the entire grow cycle, veg and flowering.

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?

Grow Technique
I have a short tent so the plants shouldn't grow higher than 70cm. What would you recommend to make sure it doesn't grow long? Maybe flowering early?

Ideal 12/12 from seed strains?

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

The FLIP
Getting ready for the good ol’e flip. What do most do you guys do for the light schedule? Is it better say (on/off) 12am/12pm, or 6am/6pm. Worried about daytime activities in that room. My schedule will accommodate just about anything, so what are you thoughts?

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?

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?

One main cola or multi nodes?
On a 12/12 from seed would you remove all side shoots to allow for one fat chunky main cola or just let her do her thing? First time using this method. Advice would be appreciated.. thank you 👌🌱
