Take pictures with out the lights on, i PERSONALLY would top them now

I topped 2 days ago the one plant in the middle i think it was light burn so i put the light higher and the yellowing is slowly going away

When should i switch to a 12/12 for flower iv been waiting because i also have 2 autos in the tent and i hear 12/12 is not good for autos any suggestions

.

I agree with Bushbaby, I'd top them again at the 4th node. You're going to have tall lanky plants if you flower the way you are.

You're not ready for 12/12 yet.

Ok ok so how much longer before flower how would you do it. They are pretty tall lanky any suggestions is great its my first grow

.

I would top above the 4th node (where you have two good branches growing) and put into flower when you have two or three new nodes growing above the top. Bring the height down.

Maybe 2 weeks - 3 weeks.

Ok i got it i did top 2 days ago so around 2-3 flipped to flower
