a pic of your setup would help greatly.

would def fim/cut them, raise your light like 3-6 inches and it will cause them to stretch, but in the long run when your deep into flowering it will give light under the colas. i didnt fim and i so wished that i did because i have a decent main cola n all but i was wanting big buds. my plants are staring week nine flowering and are still less than 2 feet tall. keepin it small
