Just so no one gets confused. Let's make sure everyone knows there is a difference between preflowering and flowering. Preflowers will show up, tell you sex, but it does not mean your plant is done vegging. Preflowers show up this time of summer for me every year since my plants are mature enough to flower. Now if it is throwing 3 fingers after it was already throwing 5,7,9 fingers you 'may' have a problem. Maybe not. Lets see some pics. But preflowers are nothing to worry about. I wish my plants would start showing preflowers, I've been waiting.
