First time grower here. I'm growing CBD Critical Cure. Dispensary where I ordered the seeds says flowering should take 55 to 60 days. I put it to 12/12 cycle about 8 weeks ago (57 days). Buds are looking fine but I don't have a microscope to determine whether or not it's mature enough for harvesting and since I'm growing first time, I don't really know how to look at the pistils. Few of them seem to be white, mostly dark though. My aim is to get as high CBD content as possible. Is it ready for harvesting or should I wait for another week?
