Question: Lighting time change stops flowering???

[Alaskan1]

Hey all,

I have 2 plants each of 4 strains going. I colloidal silvered one of each, and moved them out of the tent. Those sprayed are now covered with pollen sacks. The 4 female in the tent were doing fine, but I switched from a 22:2 light/dark time, to 20:4 light schedule right after they started blooming, because I had some vegetable seedlings I needed to move into the tent.

Anyway, it's been about 3 weeks, and the girls stopped flowering. Ugh! I've grown autoflower for years, and have had no issues with flowering stopping, but then again, I've never switched the lighting schedule part way through.

So, any suggestions? Leave the light the same, and hope the flowering kicks back on? Or change back to the original lighting schedule? I don't really want to do that, because the vegetable seedlings need more of a dark period.

Has anyone ever had this issue before where a light switch screws autoflowers up?

Thanks.

If you can give them a longer dark period, then do it. It will kick the hormones in the plant to flower. 12/12 for a couple days aught to do it! next time, I wouldn't suggest playing with the light schedule too much. It can slow things down, or stress them and give you other problems, like hermies. I have either run 24 the whole grow or 20/4. I have had some plants just not want to kick into flower and the 12/12 really gets em going!

Thanks Briman. Okay, so I'm going to go 12/12 for two days, then back to a different lighting schedule. I've always grown cannabis with a 20:4 cycle. However, now I've got vegetable plants in there, such as tomato plants, etc. You do vegetables, right? I think we chatted about vegetables last year on this site. Anyway, my reading tells me that I should give the vegetables a minimum of 6 hours darkness. Do you see any reason when I switch back from 12:12, that I shouldn't go to an 18:6 schedule for my vegetables and cannabis? I'm simply growing a seed crop of cannabis (4 varieties of seeds), so as long as I get seeds I'm good. Or do you think my vegetables would be good with only 4 hours darkness? I don't want to herm my cannabis, but I do want my vegetables healthy!

For what it's worth I grow mine at 18/6 from start to finish.. Not vegetables

Thanks Ripper! Maybe I'll try that this time around to accommodate the tomatoes and such. Sounds like most do autoflowers with longer light schedules. How is your yield with 18/6?

So far so good alway 2 ounces per plant or more
