Potential growth of buds

Hi all,
At the moment i have 5 plants growing on my window-sill.
Since they are growing i haven't turned the plants at all so all leaves and buds are growing towards the window.
The last weeks i place my plants on the balcony sometimes, the problem is that the plants have one side where the buds are much bigger than the other side.
My question now is, should i turn my plant so that the small buds grow faster or should i leave them and let the big buds even grow bigger?
Is the growth of a small bud faster than an already big bud?
Thnx in advance!

P.S. I'm Dutch so my english is not that good, sorry for that.

I've had this happen with a plant that was lst'd. I had tied the top of the plant over and left it so only half of the plant was ever exposed to full light. What I did was tie the plant down with zip ties in the opposite direction and every day I'd tighten it a bit while also tying down any new apical tips. Since you're already in flower I wouldn't do this. You could rotate them each day if you wish. This would help in evening out the size of the buds. It may not help much though depending on how close you are to finish. Good luck

First of all thnx for the response!
I'm quite close to harvest, the problem of rotating is that some of my plants have grown for so long against the window that much of the leaves are verticaly(I can post a picture of them tomorrow)
so when i rotate them, the leaves will be with the under side faced to the sun, I think it take to long for the plant to straighten their leaves to normal and they will miss a lot of sun.
At the moment the front buds(the buds on the window side)are much bigger than the ones on the back.
So i was wondering would I get more grams if I let grow the big buds even bigger or should I put the small buds in the sun?(like a child is growing faster than a adult)
Thnx again!
