I cant seem to figure out whats causing the look of these leaves. Its across the whole plant just about on every kola. I have 4 total plants. Only 1 has flowered for a week. I grew em all from the same batch of seeds at the same time. The other 3 at least look great but I did find fungus gnats today on the one flowering potted plant thats 6.5 ft tall. Any ideas whats up with this though?
