Hermi Ready For Harvest?

Veg for about almost 3 weeks.. few plants that have been Flowering for 6 1/2 weeks 7 wks. 2 of which have seeds that are already fully developed (some have fallen, some are hidden in seed pods; but are fully developed) So my question is does that mean the buds are done at this point because the seeds are mature? Trichomes seem to be going whiter (no scope X) thou they appear sparkling now... Pistils are about 45% brown... Not sure if the mature seeds mean to chop her or does that not matter??

I'd highly recommend you buy a scope. You really can't judge any other way. looks like there is still new growth forming and if you have new growth than it will need to swell for you to get the most of your harvest. On the other hand if it is dropping seeds it may be fully mature. The un-experienced must rely on the proper tools!
