The Q&A Archives: Transparent Spots on Pepper Leaves

Question: After examining the chile peppers I just bought I noticed some greyish spots on the leaves. I notced the spots when I bought the plants but thought they were just dust or dirt. When I tried to wash them off I realized that it wasn't dirt. The spots aren't actually dusty or moldy, just dust colored,and under closer examination appear somewhat transparent. I have read through some descriptions of chile pepper diseases and couldn't find anything that quite matched what I have. Outside of the dust colored spots there doesn't seem to be anything wrong with the plants. What do you think the problem is? Is there a treatment? I'd really appreciate any help you could give me as I just started growing peppers and am quite anxious to have them work out well.

P.S.- The pepper varieties are Orange Habanero, Red Savina Habanero, Golden Habanero, and Scotch Bonnet.

Answer: It may be a case of sunscald. Young plants that aren't properly hardened off (gradually exposed to the elements after a cushy seedlinghood in the greenhouse) often suffer from overexposure to sun. The scalded tissue is dead tissue, so give your little seedlings some TLC. When you water, do so with a dilute solution of a seaweed-based fertilizer, which contains lots of trace nutrients to help improve plant health. Be cautious of overwatering, too, because peppers do not grow well in damp soil. For other chile growing tips, check out our database. Or feel free to ask more questions! Good luck --
