I was going by a chart from Mr. Grow it. & I also have the General Hydro one. So I was only using half of recommended on the trip. And I even started off doing the same when I introduced the kool bloom & bud candy. But for some dumb ass reason when I thought I was at end of flower I thought what the hell. I'll give them the max to boost it. I guess because I thought at 9 weeks I was late on starting the flush (or straight water. No nutes) & wanted to give wr a bump. Then I found out Blue Dream can go to 12 or more weeks. Lol. So yeah, you live & you learn I reckon. My next grow I'm going to keep the nutes to a minimum & see how she does. Cheers.
