Hey there… are you sure your #5 bottle has been dispensing properly ?
This looks spot on to a Calcium deficiency, one of the most accurate depictions I’ve seen on AG compared to the pics:
Orange tips and burnt orange spots.
If your bottle #5 has been dispensing, you may potentially do a pH health check and make sure it’s calibrated. Maybe Calcium isn’t available if the pH reading is too high, but others like Nitrogen, Phosphorous, Potassium, and Magnesium are? Just spit balling.

Just keep an eye on the spots though… make sure they aren’t progressing any worse or further up and you should be fine either way! I would still possibly investigate though, as I haven’t had a deficiency show up this bad in both my grows yet, knock on wood… only a few tiny little spots barely visible in pics.
