question

I just harvested 5 girls that had a main cola and lots of branches with buds,however my remaining 2 only have a main cola with no branches. Is there a reason for this or is it just based on the strain or something. I ended up with about 4 ozs off of 7 plants. 2nd grow. Thanks guys

only one main cola per plant? what varity.

Bag seed (mids) no topping was done on any of my plants. I have 2 2ftrs left and they are just 1 2ft cola a piece. All the rest of my plants had branches with buds but not these 2. I guess a 2ft cola isnt that bad, but I was just wondering what caused it not to have branches.
