My dilemna. One auto, one photo

So i got a few seeds from Attitude a while back and bought a couple different auto seeds. I decided to plant one Ultra Lemon Haze (auto) and one freebie, Lemon Skunk, which I assumed was a auto, female.

Cut to day 34 or so. My auto is in full flower, my freebie started to develop a few white pistils at the time, but still vegging hard. It's still considerable shorter then the Sativa dominant auto. I thought it was an auto (till recently) and tried cutting my lights to 17/7 fro 18/6. Hoping this would be enough to turn my Lemon Skunk.

I am now convinced it was a regular seed, that fortunately is female, but not an auto. It actually looks fantastic and still has some preflower pistils (?).

My question. I have 1 other auto at about 14 days and two photos at about 7 days. My original plan was to let my 14 day auto flower, wait for the 2 photo varieties to veg enough before kicking the lights to 12/12. I would prefer not to cull the two photo stains if possible.

I realize this is a vague scenario, but any recommendations. Thanks

Only if you raise your sword and yell, "By the Power of GreySkull"...!!!

Seriously tho, you could either let your photos veg while you grow out your autos, or cut the lights back to get the photos to flower - at the expense of your autos. Or separate them. I think thats about your only 3 options.

Just run your autos at 12/12, it works pretty well. You won't get a world-beating yield, but as an auto, what did you expect? Seriously, it will work. Photoperiod cannabis is the best, autos have a place, but I'd never cull a photo in favor of an auto, never ever ever.

Thanks for the replies. I think I will maintain 18/6 till my photoperiod seedlings veg a few weeks. I'm doing a good job keeping my ULH in check by tying branches and minor defoliation (I know a auto no-no, but it works for me and it looks good) My lemon skunk is more squat with lots of growth. I've almost supercropped it by accident. I think I should be able to take my lights to 12/12 in 3 weeks or so and everyone will be happy.

I was worried I might stress my auto. Mainly the Lemon Haze that has been at 18/6 it's whole life (35 days haha) and for the next few weeks before changing to 12/12, since its about two weeks into flower

I ran a Sweet Dark Devil Auto at 24/0 for a long time into flower then put it in the 12/12 tent, it didn't seem to mind at all. I gave that advice based on personal experience, it really didn't seem to change the rate of development at all. I can't be sure, since I haven't ran that strain before or since, but I doubt you will have a problem, based on my personal experience.
