1st grow

What week of flowering are you in, week 3 as stated above? If so that's way too early to harvest imv. Humidity you'd want 40-50%, 70% is inviting mold issues in flowering. Looking at the video (slow down when panning the camera around) there looks to be a lot of foxtailing. I'd recon this was due to past heat issues. Looking at them, I would not be thinking about harvesting for 2-3 weeks. I'd be hoping to get conditions under control, and for the foxtailing calyxe's to get a new flush (or two) of pistils and thicken up.

Don’t rush to dry it out. I would maintain a humidity between 50%-60%. Make sure there is plenty of air circulation in your drying area but not blowing air directly on the buds. It should take you 10-14days for it to completely dry out. To test this take a smaller branch and bend it. If it snaps then it is ready. If it just bends then there is still moisture and let it sit for a few more days. After you have dried it out it is a very important step to cure it. Trim the buds and place them into a sealed jar. Open the jar 1-2 times a day for a period of about 20 mins. Seal the jars back up and leave in a dark cool dry area. Do this for another 7-10days. You should be all set then. Good luck!

My best tip for a new grower, is to dry it slowly around 60% humidity, drying shall take around 10 days minimum. Most of new growers turns their ganja into hay on the drying process because they always dry it to fast ... Don't rush your weed ;)
