Hey man first of all great looking plant :) She's really coming into maturity now. Don't worry about the new growth. It can happen normally is it fox tailing by any chance ? Depending on what Trike potency your after I would say these are due harvest in my personal opinion. You can let the new growth grow but beware of seeds in the later stages of flower. our ladies can self pollinate themselves if you give them the time.
