Hi growers! I posted a few weeks ago about her and realized that I was the dummy, I forgot to flip her into flower. Now she’s been flipped and still not flowers. Her leaves are starting to discolor. What am I doing wrong? She was planted early to mid April.

How long ago did you begin 12/12? If it's been more than 2wks better check your timer or your light. Do you see female parts? I sure hope so.

Should I change the timer or is this ok? I’m using the set already built into the tent. @Galgrows @MileHiGhost

Am I reading this right? 12am-6pm on =18hrs of light? They will never flower with that schedule. 14hrs or less you'll see them begin to transition.

what your showing is an 18hour light cycle on with 6 hours off, you need to change your lighting to be 12 on and 12 off, flowering wont start unless the light changes which is represented by season changes.

I do 11 on an 13 off for my first 3 weeks, but 12/12 works just fine.

I use regular seeds so I need to gender before they get out of control.
Once the flower transition is done I go 12/12 till flush then I go 13on 11 off fer the last 3 weeks. More growth. Then Paul Bunion!!! Timber!!!!!

No shit... 13 on last three weeks works for you? I've been doing the opposite to mimic late fall lighting schedule. but this 13 on is interesting whats the PPFD on this schedule?

I'd take the plants out, put yourself in, close everything up as it normally would be with lights off. If you see anything but pitch black, there's your problem. The discoloring there looks like a phosphorus deficiency, the plant could be shifting its nute demand for the flip but maybe having an issue with leaked light when its supposed to be dark.

Okay let's get some clarification. You led by saying you flipped her. Exactly what action did you take that you are calling a flip?

I found it helps expand the calyx's, takes a good month or two to revert to veg! Extra light means more growth

Also helps burn out left over nutrients. :)

I’ve done this. The only light that I can see is due to the threading on the tent, very minimal light is escaping if I could even call it that.

I thought I changed the light schedule to 12/12 using only the tent “flowering”option. One user said the settings on the tent is wrong. So now I’m going to manually change it to 12/12. Is there something else I should do?

No, change the lighting schedule manually to be 12/12, there's also community build times you could use but personally i do mine manually. after fixing the light schedule wait about a week and check for flower growth.
