There are pale patches and little brown spots on the leaves of my lemon balm plant.
Here are two pictures.
I recently transferred it from a six inch to a twelve inch pot. In the six inch one, I was watering it every morning until it dripped. Since it needs way more water for that to happen in this pot, I no longer water it every day; I just stick my finger in the soil knuckle deep, and if it doesn't feel as moist as it should, I'll add water. Was doing two cups every time, just started doing four this morning because I figure it needs to soak all the way through the soil, and even that doesn't cause dripping. Edit: I'm seeing moist patches forming on the outside of the bottom of the pot (it's Terra Cotta), so the water is definitely getting down in there.
It gets a decent amount of sun, mostly in the middle of the day and early afternoon, but it's difficult to determine the exact amount due to a bunch of oak trees in my yard.
I planted the thing roughly two and a half months ago, but totally forgot to keep track of the exact date. Lesson learned. The pale bits were appearing with much less frequency in the smaller pot.
Edit 2: Forgot to mention that I've been battling it out with these little orange worms for a little while now, they appear on my plant every now and then and seem to be very happy whenever it increases in size. Those are probably my problem. Can't seem to find what they are or how to get rid of them, though.
Edit 3: As of today I've also seen little flea like bugs and little black and white flies, all of which I'm pretty sure are contributing to the damage, which seems to be getting worse. Currently looking around for food-safe insecticides/repellants.
Edit 4: There's a little orange insect eating an even smaller black fly looking thing on one of the leaves, which makes me think that the black flies could be the issue and killing the orange things has been a mistake? The fly looks like it might be a soil gnat...
