My first grow was a success, though I burned up my fan leaves with too much bloom food too early in flowering. I stressed over every droop, bend, and leaf curl and was so paranoid about overwatering that the first 4 weeks was like growing in the Mojave desert. Got about 11 zips off it under 400W - despite me, not because of me. So, of course, now I'm Mr Smarty Pants who knows how to grow weed, right? Well, this time around, since I'm such a natural grower and all, I just set 6 seeds, assured I'd get at least two fems. Well, I got one, and it's a leggy stark bitch with about a half dozen bud sites and 3 miles of stem. So, my current grow blows, and any pro would laugh his / her ass off at it. In fact, I'm laughing at myself while typing this..
And I think the high male ratio was from putting my superskunks in pre-ferted MG soil -- they did not like that at first. They grew into it and looked fantastic before I pulled them, but had a long stress period for sure.
So I guess the moral is... if your first grow turns out well, don't be suckered by beginner's luck.
