Hey dude.

Nice grow show.

I too grow in a small space, 90cm x 90cm x 150cm. I found a few things out the hard way when I first started growing. The biggest issue was space for the 7 - 8 plants I expected to grow in there.

As the plants get bigger they will fill out. The strongest plants are the ones which begin to take over the tent. This in turn reduces the light the weaker plants get and stunts them.

It would be a good idea to lollypop the plants as you will reduce the diameter of each plant. Just take the smaller branches on the lowest part of the plant.

These branches produce very little bud, mainly what they call, popcorn buds. These buds are of no real value and most of the plants energy is better spent at the top and the tops of the stronger branches.

I had to cut my tent down from 8 plants to just 2 in my first grow because of over-crowding. The plants I cut down did give me some bud but not much. What I did notice was the explosion in the remaining two strongest plants. It was quite obvious that when the plants were fighting for the light they didn't start a full effort into bud production.

As soon as the plants were removed the last two packed on bud like crazy. So I guess what I'm saying is, sometimes less is more. I can only fit 4 normal plants in my tent. I can fit 6 autos, even though I have 7 at the moment.

Perhaps some Low Stress Training might be a good idea so you can manage your canopy better. This should give a more even distribution of light. Just tie the plant down slowly with some twine attached to the bucket. be sure not to choke the ladies though. Keep the twine loose around the trunk.

Personally I wouldn't top the plants when they are already in bloom. This could stress them out too much and they could hermie on you. LST is much more comfortable for the ladies.

Anyway, I hope this helps.

Take Care
