How should I go about now?

Hi!

Im pretty new to this thing. This is my third grow. My setup is: 1,2x1,2m grow tent, 600w cooltube lamp w/strong outtake fan, passive air intake, one circulating fan, 4 homemade hydro "buckets" with external air pump for bubbles, temp/hygrometer. I have 7 plants (3 buckets with 2, 1 bucket with 1 plant), all are Barneys Farm LSD and nutrients are Sensi Grow from AN.

The plants are now 7 weeks from seed, and Im thinking another 2-3 weeks before switching the lights. They were a bit slow at first, but I think they have come along nicely.

My question is now; Does anyone have any good input on what I should do next? Pruning? What to cut off, what to leave?
The plant in the single bucket have been topped once, the other ones have grown without interference. I want to get good yield, and of course as potent as possible. Last time I did the same grow with 8 plants (2 in each bucket), and double topped them all, which resulted in a catastrophically low yield.

Here is a few photos (sorry for the bad quality).

Seems pretty cramped in there, I'd suggest on your next grow to use the scrog method. Plants are looking good though from what i can tell. (Pics are tiny on my cell)

whats your temp in the tent

other than topping i wouldnt cut anything. try topping them all early next tine to maximize yield.

The temp is stable around 25°C (77° F).

So no pruning? Wouldn't all the leafs put the buds in the shadow?

I'm pretty sure the buds will grow beyond the height of the leaves eventually. I wouln't prune at all but that's just me. nice grow you've got there.

You can tie down the larger tops, keep them tied down (move the string, wire etc) until on your second or so week of 12/12 then let em go and you'll have a bunch of colas around the same height I wouldn't cut anything off though, not much recovery time.
