sorry man i dont know much about harvesting but a good flower time to harvest is 8 weeks for most growers....alot of growers harvest the top half and leave the lower buds so they recieve all the light so they can finish up...i too am growing...on my second round.....i didnt do so well my first time around and never made it to harvest....but those ladys look mighty nice....i hope my buds look as nice as yours when they start coming in .....peace
