I have an outdoor grow that appears mostly healthy, but in the past week I've noticed a few things that I'm not sure how to deal with and I don't want to overreact to what may not be a major issue.
The first issue is that, on one plant, random leaves appear to be yellowing. I know it's normal for older fan leaves that aren't getting as much light to yellow and drop, but that doesn't seem to be what's happening.
There are also some white spots, lines, and even some holes with white edges, which I suspect are insect damage. One plant definitely has more damage than the other, but the overall health of the plant doesn't seem to be affected yet. The same plant, though, has some pistils turning brown which I know is normal, but seems to be happening earlier in the season than I expected.
I took pictures of the insects I noticed, except for some shiny gold/green flies which wouldn't stay still enough for a picture. There is also a spider species that is sort of cocooning itself inside the leaves, just a few of them, and they don't seem to be doing damage. That's another reason I've avoided insecticides so far -- I don't want to kill predator species if they can help control the problem.
The growing medium is generic top soil, peat moss, and sand which I've fertilized once every 2 - 4 weeks with a combination of urea, Espoma Plant-tone, and Espoma Tomato-tone. As the plants have moved into flowering, I backed off the urea and used more Tomato-tone. I don't think it's a nute deficiency or nute burn, but I could be wrong.
Anyway, pictures are worth 1000 words, so here's some of the first plant:
And the second:
Any advice would be greatly appreciated.
