Pretty sweet grow dude. I see some things I would do differently, but I have to give you props on a excellent room and an incredible yield! + rep. I hope you cloned that Vanilla Kush pheno, I don't think I need to tell you that's heavier than your average plant. Have you ever considered a light rail? 200 bucks, give or take, saves you a lot on the electricity bill.
So are you sure your plants hermie'd? I remember the first time I saw a calyx grow out of another one I thought it was balls too, but after waiting half a day or so I saw pistils shoot out of it. It's just the mighty awesomeness that is H&G. And I know your cousin likes Fox Farm's, and while I enjoy many of their products, I have done a comparable side-by-side, and the House and Garden wins out by a long shot. While the number of plants weren't the same, the results were obvious for anyone to see, the H&G gave bigger, fatter, chunkier nugs, with a much better perfume than the Fox Farm gave. The fox farm booster pack is cheaper than Bud XL, Top Booster, and Shooting Powder, and it works great, but H&G keeps a more stable pH, it doesn't use a base with chunky particles that do not do well in a hydroponics set up, not to mention stronger smelling and tasting nugs. Fox Farm makes some fantastic soils, though. But VermiCrop is giving them a run for their money.
If you noticed a lack in flavor or taste in any of your buds, start bugging your local H&G rep about their "Cell Splitter" or "Cell Excelurator." It's not available in the US, but the more you bug them the faster it gets on the market. A completely fictional statement would be "If you ask a rep about obtaining the Cell Excelurator, he would tell you he already has some you can have for free." But once again, that is just a fictional statement. This product is amazing and provides lots of humic acid, carbon, beneficial bacteria, carbohydrates, silica, and some other wonderful shit. If you can't get any of your grubby sticky fingers on this product, Liquid Karma by Botanicare actually makes a wonderful substitute. It doesn't have any silica in it, but I see you are already using grow stones with silica in them, very expensive, but also very nice. However a liter of Dyna-Gro silica supplement is only $11, and using expanded clay pebbles is a lot cheaper. I would also consider adding something like "Sweet: Raw" by Botanicare to add some more frost and flavor, sufficient cal-mag along with your carbohydrate will ensure a full-bodied flavor. And if we are adding additional carbs, we might as well add some mycorrhizae, I like Mykos, but I hear Great White goes a lot further.
I think if you kept doing exactly as you are, you are bound for success, you've already achieved it once. This is just my 2 cents. Sharing is Caring
