Leaves spots

Hey, bro! 👋😇 It's not a problem with the plant and not a problem with the nutrients, it's a problem with how carefully you're watering! You're watering your plant and water is getting on its leaves, all of this is happening with the lights on, and the water droplets act like focusing lenses, intensifying the light's activity in the spots where the droplets are! These are burns, my friend! Please be more careful and attentive - avoid getting water on the leaves, and don't spray the leaves when the lights are on! You can only foliar feed when the lights are off and only during the vegetative stage! These burns won't ruin your harvest or cause problems in the future if you're careful with your watering. Even if you accidentally get water on the plant, take a cotton swab and gently touch the droplet with soft, pinpoint touches to remove it - the leaf will remain undamaged and look great! But don't leave droplets on the leaves with the lights on - that's guaranteed to cause burns! 😇👆 Good luck, bro! ✊😇

Could be a calcium deficiency but can't be sure. Ruling out nute burn as that usually starts on the edges.
