How do I fix?

Hey everyone,
first time growing outdoors in AUS. Plants have been mainly healthy until today when I noticed the below on the leaves. Not sure what to do to fix…
Feeding has only been seasol and seasol power feed every other feed. I’m starting to see yellow dots on the leaves and some brown burnt out areas not sure what this means?

You've got bugs. Spray the plants.

With what?

Look for “ garden safe “ products - designed for edible plants , vegetables , etc.

Otherwise you may end up toxifying your smoke.

Food grade citric acid is cheap and effective.

Looks like pests

You're still in veg, no flowers, so you have a lot of options for spraying. Once in flower, your options are more limited.
