What’s Wrong? Natural or Nutrient Burn?

Grow Cycle Flowering
,
1

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
  • Location: Southern US, hot and humid
  • Temps: Upper 70s daytime in October

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)

Thanks

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?
