Spots on Salvia Seedlings - Knowledgebase Question

Question by smp3411

I have over 100 of your Heirloom Blue Bedder Salvia growing under lights. They have been doing very well but this morning on 2 plants I noticed very small white spots on the top of the leaves. I have never experienced this before. The rest of the plants still look OK but I'm worried they might have something? I'd really appreciate a suggestion on what to do. They are about 1" high at this point.

That's a lot of salvia! If the spots are fuzzy looking, then it sounds like a mold problem. Mold forms in humid conditions, when plants are crowded and air circulation is low. Remove the molded plants, and pace a fan near the seedlings to dry the leaf and soil surfaces a bit, to keep mold from spreading.

If the seedlings are tall and close to the grow bulbs, they may have been scorched. Scorch spots are white and wrinkly. If the seedligs are that close to the bulbs, it's time to raise the light fixture.

I hope this helps!
