Hey guys! First time grower here. I’ve got two bubblegum autos growing indoors. One is doing great but the other showed these signs early on but didn’t appear on new growth so I didn’t think much of it. But it’s becoming more noticeable on lower leaves as the plant gets bigger. I’ve been reading for weeks about what it could be and to the best of my knowledge it looks like leaf septoria. But from what understand that only occurs on outdoor plants? Any help at all would be appreciated. Thank you all.
