Brown Spots On Leaves -

Hello, Plants are getting brown spots on green leaves, don't know if it is bugs or fungus?
growing outside

Looks like leaf hoppers to me

Bugs for sure. You need to take a scope to it and determine what type. I bet there's more than 1 being outside. Depending on how far along you are in your grow, will determine what to use to help but bugs outdoors will be a tough challenge.

Looks like small grubs or caterpillars sucking the leaves. Check the stems with a light to find the little critters.
