I have 2 Lifter CBD plants. Started outdoors then came in when the weather started cooling down for the fall. They are now under full spectrum LED lights. Approx size of plants are 4 ft. They have spent 7 weeks in bloom. Pistils about 75% brown. Trich 60% milky, 20% clear and 20% amber. I have flushed for the last two weeks with distilled water. It it ready to harvest? I'm looking for a good painkiller/sleep combo. I do not care about excess (+.03) THC levels. Never have grown CBD before and need some advice on the best time to harvest for what I'm using it for.
