If done early in life they will double to triple in yield but if done late, shortly before harvest it will have the opposite effect. If those were in my garden I'd let them go as they are.
This is what happens when you FIM top a top 1 week before flowering. 2nd pic is a top from the same plant that wasn't topped. See the difference? If it was your only top on the plant, you'd be better off leaving it un-topped. My plant had like 7 or 8 main tops, and we topped a few and left the others normal to compare yields. Follow the log in my sig i'll let you know how it turns out when i harvest in like 3-4 weeks.
