Just caught up and finished reading the thread, looks like you are doing fine. I am gonna check out that AC Fan myself. One thing I have learned the hard way is, when you think those buds are done, give them another week or two, you will be surprised when you get a second push. My buddy showed me 10 grows of pics when he thought they were done to leaving them go 2 more weeks and getting huge increase on bud yields, he doesn't even use a finisher until he thinks they are done and then feeds them the finisher and unsulfured Molasses mixed into warm water for the last two weeks. I took mine too early, should have gave her few more weeks.
