Could be PH related, or a light burn if you're spraying her while the lights are on. Either way, keep and eye on it - doesn't look too serious but it's still good to take note of.

hello you do not want to remove any burned or browning leaves , until you are sure the deficiency has been corrected . the plant is using up this lower branch for a reason and if removed before the issue is corrected it will just start on another higher up branch or leaf

It could be from over watering or watering to frequently. Your also pushing your Ec a tad high for an autoflower. Your soil will probably just be running out of its nutrition so you are right to start adding your fertiliser. I would water, till run off, let dry for top inch of soil before watering again.

Could be a little ph. Loss of light, or just moisture. I remove those myself. Good luck

Yellow leaf edgesI have a couple plants that are about 5 weeks old, and one has started getting yellow edges around the leaves. I feed them with worm tea, kelp, and calmag every other week, but it's a light dose so I think this is a deficiency and not a toxicity.Leaves. Edges burnt
