i would start buy adding lady bugs or peresimilis on each to stop infection from spreading then i would only use organic tea whit a lots of nitrogen sea weed extract + molasses

You have spider mites mate I watched your video at the end of this week and at the bottom as your watching you can see webs ???? I would trash that plant if I was your or start using something really strong to get rid of them hot sauce garlic and soap is what I use ! Best of luck with your battle your gonna have

I also see some insect bites into the affected leaves! Calcium deficiency usually starts on new growth First! Rust fungus shows up as spots like that on leaves could by that... those bites could be from fungas nats. Which come equipped with affecting your leaves like those splotches ... Are any insects apparent? Do u have a microscope or jewelers loupe to give the affected leaves a thorough look at? Could be a few things but those bite Mark's got me on the rust fungus or fungas nat conclusion.

Looks like a calcium deficiency. Either by lockout or not enough. Since there's no pH we really can't give you a definite Yes or No but I'd say fix that pH(assuming it's off) and go from there. Only use water until you get the pH in check. Happy growin'! ✌️🌱🌲😎💨
