The Q&A Archives: Leaves Of My Tomato And Hot Pepper Seedlings

Question: I started my tomatoes and hot peppers from seeds. They came up and developed their first two leaves without much of a problem. Now I noticed that the leaves have curled on the ends and are turning brown also. What is the cause and is their a cure?

Answer: If the tips of the leaves are turning brown I'd suspect fertilizer burn or lack of humidity. I fertilize my seedlings every time I water, using a quarter-strength dilution of liquid fertilizer in place of plain water. This method provides a constant source of nutrients without the potential for overloading the soil and burning the plants. If you're using regular incandenscent lights, the bulbs may be too close to the plants, excessively drying the air and radiating too much heat. The affected leaves may or may not fall off. Either way, it shouldn't cause problems with your peppers and tomatoes. Young, vigorous plants will replace lost leaves.
