Switch to 12/12 or let them ride.

More than likely the sativa will outstretch the indica during flower. If your plants are about 1/3 the height of your tent I’d flip it now or you’ll end up too close to your light source. Once you get to close to your lights you’re looking at possible mold, burn, and foxtailing issues. These are things you need to avoid. I would not cut off any leaves until after the stretch, and then be very careful in doing so. This is what will give you big bud.

Yes mate. Switch immediately. These plants will double in size once in full flower.

I think its a good time to flip. If you veg any longer they are really going to stretch, gotta think of your space limitations. I'd keep the air movement up and try not to take off to much of anything. just the stuff touching the soil. More leaves = More growth

Strip and flip. I try to deflo to the last 3-5 pairs, this slows the stretch down. Allows for better air flow and keeps the nodes tighter. Try what you want it's hard to mess up. Learning is fun.

Plants tend to stretch 1.5x to 2x and even 3x for sativa dominant strains, so I would say it depends on what you are looking for personally I would flip. Happy growing!

I'd veg them for a couple more wks but that's me,I like big plants.Another 2wks should give you at least another oz per plant. I'd remove a few leaves,no more than 5 off each. You'll see how some of those fan leaves are covering side braches that will grow a lot more if they're given more light.You can see they're very wide plants that will have strong packed side braches so remove the odd leaf that shade them.They'll more than likely double in height if you switch them now but another 2wks and the tent will be full.I guess 2wks for another 4-6 oz.
