Looking pretty damn good man, I think thats gonna be some good smoke, mostly cause its your first successful grow. Do not try to harvest based off of flowering time! There are a lot of ways to see when the plant is ready but the best is to get a jewelers loop. Amazon has them pretty cheep, look for like 40-60x magnification. Take a look at all those trichomes, with the loop, now they will all be clear. But will turn to cloudy then amber, you'll want to wait until about 15% are amber. When to start looking at trichomes? Pay attention to those white hairs, when they start to curl in then you should be checking the trichomes every couple of days.... If you don't want to get a loop then wait till most of those white hairs are curled in and brown. Also don't be alarmed, your plants are dying so leaves from the bottom will start to turn and fall off. Grab them and remove them from the area. Never throw them in your trash any other trash but not yours.
