P.S. ... good luck with your Willie ... go light on the nitrogen, she's easy to over-feed, very tall, top her early, if you don't have a lot of height, (my cabinet stand 7.5-feet tall) ... I flowered mine for 14 weeks, and still never got a single amber trichome :wtf: ... my outdoor Willies are MUCH better, I really wouldn't recommend it for indoors, if you have a choice ... (Reeferman Willie Nelson = never again) ... :wtf:
image reaper thanks for info- just what I thought- i grew some willie last year outdoors and harvested last week of October and had no amber trichs- this season my plants flowered 2 weeks earlier then last so I am hoping they will mature to my liking before it freezes here- i live in the mountains above 2500 feet so early freeze is always a concern of mine- next year I will grow indica- can't go wrong with northern lights much -appreciation for your reply
