Nice WnF! Looking good!
For whatever it's worth, I've found AN support to be fantastic. I talked to them a few times. The first, I asked about a feeding schedule that wouldn't be "too aggressive". The guy literally mapped every week of veg and bloom for me with exact amounts of Grow/Micro/Bloom/Big Bud/Bud Candy/Overdirve for each res change.
I was pretty impressed, although I'm using the GH grow/micro/bloom currently since they came with the waterfarms, they're supposed to be more foregiving for noobs, and since they're small bottles, I figured I'd use them up before switching. Actually, I just exhausted the first bottle of bloom today and I'm only two weeks into bloom on two plants (although, I did have some "false starts"). It also appears that you use less of the AN than the GH, so although more expensive, I think it will even out in the end.
