Note that I have edited this entire post/thread
I no longer believe this to be a manganese deficiency, however, can't change the post/thread title.
Here are a few of pictures I took yesterday of black, mostly round dots, on many of my leaves (as well a caterpillar problem and, I believe, a spider mites issue). Oh, and I don’t want to forget the bud rot! That’s the full Monty!
You can see dark spots on the yellowing leaves as well as a few on a couple of the deeper green leaves. In direct sun those spots look more black than brown. As the spots get larger, they stand distinctly proud from the leaf surface and tend to lose their round shape becoming much more irregular. Also, in bright direct sunlight, the spots are quite shiny/reflective. That actually makes them easier to spot in direct sun.
My question is has anybody seen this? What the heck is it?
As I mentioned above, I also have a bit of a caterpillar thing going on and maybe spider mites. And yes, there’s a little webbing over one of the yellower leaves.
I grow outdoors. I used a combination of what was new potting soil last year and new potting soil. I tried to approximate a 50/50 mix. Since starting to flower, I’ve been feeding the girls Maxsea seaweed plant food, 1tsp/US gallon of water. I feed every two or three days depending on how windy and/or hot it’s been. It’s 3-20-20. Prior to flowering I had been feeding them a mix higher in nitrogen, but don’t recall exactly what it was. I attribute that to my CRS.
Maxsea has a bunch of micronutrients. I’ve been watering with the stuff for at least three weeks.
Regarding the bugs, you can see a chewed yellowing leaf as well as the tell-tale white chew marks/spots on a couple of the leaves. I’ve been finding mostly inch worms on my plants and picking them off by hand each day. I remember this from last year too. I’m retired so I’ve got the time.
Thank you in advance for any advice you may have to share.
