Hi! Pura Vida! 👋
Don't worrie buddy you do it right, neem oil cand treat Leaf Miner👍👌, you can remove the leaf either if you want because there no more leaf on her also😄, make you sure mix youre neem oil with potassium soap and make better treatment for wide spectrum of pests this for dissolve neem on the water, in case you dont have potassium soap use regular soap better if its organic...
It should be corrected it self the plant seems very healthy😎, if appear again only up your dose of neem or do it every 15 days, as preventive treatment and you have your plants clean of pests do it until week 1 or 2 of flowering state, if you considerete do you need.
Bye and many successes!💪
