What’s Wrong? Natural or Nutrient Burn?

My first grow. Been babying this girl and had good growth. Midway through flowering and now having an issue. Buds still look great but some leaves not so great.

Just bought a ppm pen and dang, dropped it on the nutrient bucket (now toasted). Ordering another.

Any thought on what’s happening to my leaves? Is it natural in late flower?

  • PH of Water: ~ 60 (do not test runoff or ppm)
  • Environment: Outdoor

You have been great at helping me on prior posts.

I realize it’s only been 3 hours since my post but wondering if you have any thoughts on my original post. I’m a little freaked about it going south.

Not sure if nutrient problem? Over watering? Something else?

I’d appreciate any help you can provide (or anyone else)

I had similar problems early in my current grow and pH was off. Are you managing pH going in and runoff pH?

Hi and thanks for responding

I do manage my ph “in” but have never tested runoff.

I can get something to catch the runoff and do that. What should the runoff ph be?

Also, my replacement ppm meter will be here Tuesday. I’ve never tested ppm.

I am a super novice. First grow was going so well. Then this happened suddenly.

I’m in coco + perlite. Would over watering this time of year when not hot cause this?
