Hi—- nice job so far! Look like it’s either water droplets burning on the leaves and/or bugs! All outdoor growers need a good IPM solution to treat the plants with—- I use a combo of a bunch of things. You will face PM, bugs, mold, etc!
I like essential oil based solutions alternating with citric acid solutions—- always spraying at night! Good luck ✌️🏻💚💨🌿
