Can anyone tell what is causing these yellow tips on new growth on this plant?
I noticed my DLI was around 42 at the top of this plant so the light may have been too strong, or it could be a nutrient issue? Using CoM Stonington soil, plant is 26 days old. Haven't added any nutrients to the soil yet.

Yellow leaf edges
I 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.

Some leaves are showing small burnt spots and slight curling. what could be? I'm currently dealing with Fungus Gnats in the grow. I applied Beauveria and covered the soil with burnt rice husk. I’ll wait for the soil to dry and then use hydrogen peroxide to try eliminate the eggs.
