Leaf spots

Those are thrips. Get some predatory mites!

I'm not positive that is spider mites. Could be sun scald too. or other bugs like leafhoppers

Good morning, This is clearly a mite infestation or something similar... Since your grow is outdoors, I recommend removing the infected leaves and applying a repellent or insecticide, preferably with natural products.

I agree it looks like spider mite. I had a bad infection this year which I managed to control with Phytoseiulus persimilis (Dragonfli) preditory bugs. I didn't get rid of them completely, but the crop was saved.

Spider mites

Looks likes spider mites. Nasty little f@@kers.

BIO - A natural pest control solution against aphids, spider mites, thrips, leaf miners, and other pests: - The high phytoncide content of onion skins and garlic skins is essential in the fight against pest insects. The treatment is most effective when the plants are sprayed in the evening. The onion skin decoction has a very short shelf life, so fresh solution must be prepared for each subsequent treatment. To prepare it, pour 200 g of onion skins into 10 liters of warm water and let it sit for 12-15 hours. Use the strained solution weekly before or during flowering until the fruits are fully developed. Dilution: Dilute the 1-liter concentrated infusion with an additional 3-5 liters of water. The strained diluted solution can also be used as a foliar feed, but test it on just one or two leaves first. Frequency: Water the plants with it a maximum of once every 2-3 weeks during the flowering stage. - Plant growth stimulant You can also use onion skins as a growth stimulant for plants. Onion skins contain growth-promoting substances that can accelerate seed germination, stimulate root formation, and enhance fruit quality. Preparing such an onion skin remedy requires little use but offers great benefits. To make a natural growth biostimulator, put two tablespoons of onion skins into 1 liter of boiling water, add wood ash, mix well, and let it sit in a dark place for 2-3 days. Dilute the strained decoction in a 1:3 ratio and use it to water the sown seeds or young shoots.

Yeah little pests.. more silica next time or give now if you have some knocking about

pests suckling your leaves... outdoors requires some preventative pest management.. and active, for that matter. If not in flower, you have options. Avoid things that are 'systemic,' like Eagle20. Pyrethrines are a kill on contact option. Whatever you settle on, best to look for concentrated bottles that you mix into your own sprayer. Best bang for the buck. neem is popular but not very effective. things that breakdown faster are probably safer (pyrthrines have a half-life of 48hours if i recall, as an example). Just because it says it's 'vegetable safe' or whatever doesn't mean it's safe to later smoke and put into your lungs... Spray anything on flower at your own risk. One of those mesh greenhouses could help in the future? As long as it doesn't attenuate the sun too much (resulting DLI).
