I'm seriously lost here. I've been brewing since July, BIAB the whole way. Today I did around my 8th or 9th batch. The first few were bottled, then I started kegging in late September. For the most part, my beers until the last two months have turned out good. Recently, I seem to have no idea what I'm doing.
My last three batches now, including the one today, have all turned out 10+ points under gravity. Even with low (70%) efficiency estimates, I just can't hit my ****ing numbers. Here's a run down of what's been happening:
October brew: West coast IPA. Missed gravity by a mile. Almost done with this keg, tastes pretty bad. No idea what the off flavor is, since I don't have any ability to really identify flavors. Feedback from experienced brewer at my LHBS was fermentation control
November brew: Blonde ale. Also missed gravity by a mile. Tastes terrible, I'm practically ready to dump this keg because I just don't like drinking it. There's sort of a weird sweetness, which the LHBS owner attributed to mash temps, as well as fermentation control.
December, today: NE IPA. For one, I screwed up my hop amounts I think - I bittered at 60 and added 2 oz each of Galaxy and Citra, at 10 and at flameout. My wort came out a nasty green color, and I'm regretting not adding whirlfloc. As for gravity, Beersmith projected 1.053, but I hit 1.04 or even lower - couldn't get a great reading, I forgot to take gravity until I had already shaken up my fermenter to aerate it a bit so there was some foam.
My mash temps weren't great - it's 24 degrees out today - but they were ok. I mashed in around 158, temps went from 154 to around 147 by 15 minutes left in the 60 minute mash, at which point I turned my propane burner back on low to keep in the conversion range and give a small mashout step.
I used priceless' BIAB calculator, and actually made the effort to check volumes this time. I don't know how to get precise measurements, I tried the kettle etching method with no success a few months back. However, I measured the height of my kettle as best as I could, divided it by the given size (11 gallons), and notched marks on my plastic mash paddle at 5, 6, 7, and 8 gallons. I barely had to squeeze the bag at all to hit my determined pre-boil volume, so it's possible I lost a few points there. However, my pre- and post-boil volumes seemed accurate.
I bought Omega Labs Hothead yeast for this batch, because I don't have time and space for fermentation control and I'm really, really hoping that was the biggest part of my issue. However, a common feel between the last two bad batches is a very thin, unsatisfactory feel, which I'm attributing to the terrible efficiency. The biggest previous suggestion was my crush. Apparently the closest LHBS to me has been having issues with their mill, and I posted a picture of my crush here to the general response of "not good enough". I went to a different store that actually specializes in brewing, and according to the owner has a much nicer mill. I had been hoping this was the silver bullet to solve my issues, but it doesn't appear to be so.
So, for anyone who managed to read this far - what do I do to make good beer again and keep the enjoyment in brewing I had a few months ago?
Edit: Water profiles. October batch I used tap water, as I did for all my previous good-tasting batches. November batch I decided to switch to RO + minerals - however, I screwed up and forgot to add the minerals till halfway through the mash. Today I added them at the correct times - 7 grams of gypsum, 2.8 grams of CaCl, and 3.2 mL of lactic acid, per Bru'n water recommendations to achieve 75 Ca/110 Sulfate.
