Yeah, from the pictures the trichomes do like a little cloudy... so you could harvest if you want. but if you're growing for medicinal purposes, chances are you're looking for a more narcotic high. i've heard of people letting plants flower for up to 12 weeks for this purpose.

It all depends on what YOU want.
Faddenator Reviewed by Faddenator on . purple leaves (PICS) plant is about 10 weeks into flowering, started seeing purple about 4 weeks ago. I seen a post somewhere from the 2001 edition of jorge cervantes grow bible that said purple leaves is possibly from too much salt build up so i flushed them out and have been giving them straight ph'd tap water for the last 2.5 weeks. The plants have only gotten more purple since the flush And i don't know what is causing it. Help What is your experience level? (first timer, novice, experienced...) (novice) Rating: 5
