Whats causing white spots on my leaves?

Hi PeggeChillum, I recently just had this same issue today actually and in the past with mites and thrips. If you look on the underside of the leaves you might be able to see them, the are small and can be green, white and brown. I find they like to hangout on the more nitrogen rich leaves. Even if you can't spot any I would treat. Spray top and underside of leaves, stems and soil with neem oil/insecticide soap or you can use water in a spray bottle with a drop of oil based dish soap. I lather my plants pretty good before lights off, I repeat a few times a week until no longer present. Since you're in early flower I would just try to hit the affected area's so you're not spraying any bud sites. Good luck !

Hi pegge, is an initial mites infestation. You can't see any bugs cause you are looking for on the wrong side of leaves. Check underside and U will see very microscopic eggs and mites, like a powder. You are still in time to gentle wash top and bottom of affected leaves with a light solution of water/Marseille soap mixed with some drops of alcool. Spray neem oil to discourage new colonies. 👊
