Hey guys... I'm fairly new to growing the magic herb, I've had a few successful harvest previously, and I've got one plant goin right now, not sure on the genetics 100 percent, its a strain from a local dispensary. Anyways, I've been using FoxFarm Happy Frog soil, as well as FF Grow Big and Big Bloom with a 250W HPS light on 12/12 for awhile, not exactly sure on what week I'm on. I know it's normal for some yellowing of the fan leaves as you get closer to harvest, but the buds don't look quite ready yet and a lot of the fan leaves are dying/turning brown. Any suggestions? Thanks a bunch!
