So here I am again and the plants are still growing. We are at 74 days and two are in fact 96cm tall. We bought the seeds from High Supplies and haven’t really seen anyone talking about this supplier.
We updated the grow tent as they were outgrowing the old one and got a new light so that it covered all three plants.
We are now thinking of putting the stunted NL into the old tent by itself and changing the lights to 12/12 on the other NL and WW. Do you think changing the lights like this will harm the plants?
I’ve added a pic of a bud site from the big NL and WW. I had thought by now there would have been white hairs…somewhere.
Thank you for your help.

Man, I'm sure you've figured out by now those probably aren't autos.... switching to 12/12 is your best (maybe only) choice for having smoke sometime in the future.
BTW...No, 12/12 will not, and never will, harm a plant in any way.

Thank you for the reply. We had wondered if this could have been the case.

We can only see the tops. And height rt now is 96cm=37+” more likely to double in size... height and width. Have you done any training? LST, anything? If not, you are about to! Get the little-un in old tent and prepare to defol, prune, supercrop, etc. cuz if they’re 37” now they will prob stretch to 6’ plus. I know WW and for the most part they are compact but they can get big if left unchecked.

If they go over 6ft then we're screwed. We had a 5 foot tent and bought a 6 foot tent but can't really go more than that , no room. I have done some LST and Pruning but wasn't sure how much I could touch them.
Ok off to setup the old tent and see what I can do with the other plants

Just for reference, this is the northern light. The white widow is on the other end and is about 2 to 3 inches shorter. You can see the little stunted NL .
Thanks for all your help

Have you ever super cropped? That would be an option if they get too tall... rub/ spin/crush the stem at level of canopy with finger and thumb til it’s flexible but not mushy then bend at 90 degrees and tie off. Gotta tie it so it doesn’t stand back up, cuz it’ll try.

No problem, when I got to AFN I had grown before but never indoors, with LED, in a tent... was a learning curve to say the least. All people on here are great,respectful, and helpful. Also when posting a pic, it’s better to choose the full image instead of thumbnail... some pics don’t translate over well and pic gets cut off. I will help in anyway I can and if I don’t have an answer for ya I’ll tag someone in who does!

I have done super cropping and broke off the main stem on the NL that is big, don't think it hurt it much. Not afraid to do this or anything else to the plants at this point kind of desperate to keep them going.
I appreciate everyone's help, i'm glad you're here to help

Yup, I’d say go 12/12. In about 14 days you’ll notice the stretch. If it gets too tall use super crop method to even canopy... it may not come to that. I would only remove top main as your last option to get to harvest. Two large ones in a 3x5 should work.
