Yea. With fox farm you should be using more like 1/2 tsp of your part A or B 2 out of every 3 waterings. Honestly I've used fox farm before and personally don't like it. I used it years ago before switching to dyna grow foliage pro and bloom and haven't looked back .

I'll concur on widow XXL being trash. Critical jack auto was pretty good and critical 2.0+ auto was surprisingly good with yield and potency. It definetly is a little prone to mold though so you gotta watch that RH%
Its fine. Just needs a few more weeks curing in the jars. Keep monitoring it every day or two and burping it if you notice any surface dampness. The smell will come back as long as you didn't over dry it.
First off. It's really common for your buds to lose their smell on first curing. An ammonia smell isn't even necessarily a bad thing. That slight ammonia smell in jars is an indication that your bud hasn't gotten too dry and is continuing the curing process. It can take a month or more of curing...
I agree with this. Especially if your plant is starting to smell bad. That's usually indicative of rotting roots brought on by being too wet for too long.
I've ran quite a few auto runs and in my opinion they are very finicky and don't handle stress like photos do. I'd avoid defoliation on them. Their end quality of potency gets impacted by stress during flower. I've had runs where getting fungus gnats led to beautiful looking smoke that had trash...
