Hi guys. white spots started to appear on the leaves of one of my plants a few days ago and it seems to be increasing in size. It appears to be a stain on the leaves that do not come off on contact. I looked for pests in each of the plants and found nothing. Any ideas?
Check under leaves and all over for bugs, if still vegging I would use some neem oil. Gives time to wash away by flower time. It will make bud taste funny using then. Good luck and happy growing 🌱
