Hello! I have a bunch of different vegetable plants that are all ranging from 3-4 weeks old. I am growing them all in pots with organic top soil. They all receive 4-7 hours of sun in a partially shaded area. Within the last 2-3 days I noticed these odd formations showing up on my cucumber, tomato, and raddish plant leaves. Does anyone know what is happening with my plants? Also, it is not happening to every single plant. And some varieties are potted together, however most are on their own.

Welcome!

Looks like leafminer damage (an insect). This factsheet from the University of Florida may be of interest:

Hi Syd, :welcome:

I'm not sure but I wonder if it's maybe Leafminer damage? Hopefully other vegetable growers will be along soon with advice and suggestions.

Yes, leaf miners. You can pull off the leaves that contain the leaf miners.
And/or you can use some Safer brand EndALL insect Killer and spray the plants.https://www.amazon.com/Safer-Brand-End-Insect-Killer/dp/B00314DYNW

If you cover the plants with a floating row cover the adult leaf miners will not be able to deposit eggs.

Welcome to NGA, Syd!

Do you find that the pots drain well enough, despite growing in top soil in pots? I like to see some water come out the bottom of the pot a few seconds after I water heavily.

(But I DON'T like water running right through a gap between the soil and the pot - that means that the soil or mix never gets wetted. If you have that problem, you can re-hydrate the root ball by briefly submerging the pot in a large bucket of water.

Often, "soil" in pots will pack down too tight for happy roots, squeezing the air gaps out of the soil so that air can't easily diffuse to the roots. "Soil-less mix" is often better for growing in pots.

If you have an occasion to re-pot them, like going to bigger pots as they grow, you might consider using a faster-draining better-aerated soil-less mix. Or adding grit-sized amendments to the top soil so it drains somewhat faster.

And yet, you have to avoid any abrupt changes in the texture of the soil inside the pot. Rapid large differences in soil texture can prevent water from diffusing from the new mix into the old root ball.
