Sounds like a nutrient lock-out, or possibly toxicity, likely due to a pH imbalance. How are you measuring the pH of your soil and water? The pictures above, that is very likely what is going on, a pH nutrient lock-out. Check that runoff ph. 🤘😤

Also looks like a phosphorus deficiency, but like the other guys said, if you aren’t watering with runoff or enough of it or you aren’t checking your runoff ppm and pH a flush is probably best

Rust inside the main fan leafs like that is exactly that ph soil and water. I would do a sledge flush and evaluate.

I'm not sure what's going on, but the tips of several leaves are twisting over and/or turning white. I don't know if it's a nutrient deficiency, nutrient burn, I don't think it's too much heat, but maybe due to sun burn? I'm not finding much luck about white leave tips online.
