Tomato Trouble - Knowledgebase Question

Montclair, Ca
Question by lisguevara

The tips of the leaves on my small tomato plants have turned yellow. The plants are still upright, but I'm concerned. What is causing this and how can I fix this. I set them out every morning for full sun, but by noon I keep them in the shade. I bring them in at night.

Sometimes overwatering can cause the tips of the leaves to turn yellow, but so can salt burn (overfertilization) or dry air. I don't think it is anything to worry too much about at the moment. Your plants will go through some adjustment as they acclimate to being outdoors all day and all night long but eventually they'll settle in and grow nicely for you.
