Ya flip those buddy. Believe me I made the same mistake. It looks like you have a bit of horizontal room to work with so you should think about maybe giving them all a good top, wait a week for recovery, then flip.
Looking again, Ya I'd definitely top first. You couldn't have more than a foot between the tops and the light right now, and they're gonna stretch one foot minimum. And make clones out of the tops if you can, then you have some real prime cuts for next round. It's not all that bad though. Longer veg means bigger/more nugs. You're just gonna have to tie them down as they stretch. Hope this helps
Peace
Derker - Holy fuck man. Those nugs look like they've got a 600 watt on them. Do you keep that light real close and temps real low? What are all the nutes you use, cuz I'm about to buy some more new stuff for this round.
