When I 1st started I burned a leaf or two. So I did cut back. My G13's were the only ones that got nute burn. The others were fine. I seemed like the leaves would turn a really dark green and the plants would perk up as soon as I fed them. Since then I've turned it down a notch and all is well. As for the feeding chart I'm 2 days in to week two. So next week it's back to the grow big and I'll get to add some Beastie Bloom for the 1st time. I'm excited to see what happens. On my 2nd grow I'm thinking about going hydro. I do the watering myself. Which has gone from a 10 min. in and out job with the babies.... to about a 45 min job each day with the girls. Don't get me wrong I'm lovin every minute of it. It's actually kind of relaxing. I'll post some pics tonight. I'm just able to see the what appears to be the beginning of buds in some spots.
