When the pre-flowering begins then start feeding bloom nutes.

1lt a day is way to much buddy drop it to about 250ml but don't water again until the top 2 inches are dry

12/12 will slow your auto plants down and possibly result in smaller flowers. It seems most auto growers have settled on 20 on and 4 off as the easiest compromise. I believe plants do require their rest and lighting at 24 on constantly, or 22 on 2 off is just too much light and not enough recovery/sleep time. For the second part of your question, that is a very interesting one! I believe plants are producing energy and adding growth slowly during the day(light) cycle and seem to put most of the noticeable extra growth during the night(dark) cycle. I am basing this on outdoor growing, so am open to opinion, however, I have noticed little change in plants during the day, but when you see them in the morning, changes/growth seems to be more identifiable. Then again, during the day you generally see your plants more often and growth may be harder to detect compared to night time, when you do not see your plants for a longer period. I think I have just found a new experiment to conduct! At this stage I believe plants put most of their new growth on at night time. Hope this helps... Organoman. What do other growers think about day/night growth?? I think you have opened a can of worms here Dean1!!!

Plants actually do a lot of growing in lights out hours. Through lights on their creating the sugars they need to do their thing. So, if their autos I would stick with 18/6. Cheers

You don’t really need the carbon filter if you’re not worried about smell. You can always hook it up later if need be. But like @gmslave said, exhaust and fresh air is important so you should keep the fan running. Don’t sacrifice air exchange for a little more space.

Don’t defoliate at this point unless you see dead leaves or yellow leaves. Nothing more is needed for your healthy looking plants. Ignoring this advice can stunt bud growth, delay harvest time, and more things you wish to avoid after all your patience and hard work. Good luck thru harvest time

Seedlings can totally be in the same tent as flowering plants. Not sure if necessary, but you can run the lights at the same time as well. Seedlings don't need as much light though, so make sure they're not getting too much from the flower light.

Looks like you stripped most the fans off already. I personally would just finish her out. 🤘😤
