srsnow......go to radio shack and look for the mini handheld microscope they have. its only 9.99. has a light and is basically made to put up to ur nugs and check the color of ur trichomes.....hair colors can be deceiving unless ur an experienced expert.....look for clear heads on ur trichomes instead of cloudy....clear to pink is when i cut....but u can look up the perfectly ripe trichome online, there r tips everywhere. thats the only way to kno for sure bro.
looks to me like u have about 35 days left on the tops. little guys mature quicker.
just so u kno for ur knowledge, id cut one tiny bud every week next week so u kno the difference betw mature and not when u smoke it after drying/curing etc. gl pimp, hulluh
