How long till harvest?

The plants is starting to ripen the flowers , the time were u gain half of the weight and the cannabinoids are creating into the weed. Start flush and wait longer u can, she need 2/3 weeks, if u are obliged to cut down i suggest you to do some extract from it cause it will not be so good to smoke. Sorry for my english, hope to help u ✌️🏽

1-3 weeks I'd say, only the higher end. Hard to say a lot without knowing the strain well. The cold I wouldn't worry, if you're in an area that may have frost, let it come. 1 or 2 frosts is okay but after that I'd chop it down. Your bigger worry to make it to max potency, is to keep the buds from being soaking wet but allow airflow. Bud rot is so horrible. I generally will chop a plant down the first time I see bud rot. Not worth losing a flower a day just to let it grow a bit more. Anyway, good luck
