Brown spots on my young tomato plants #749860

Asked May 14, 2021, 7:42 AM EDT

I have some potted tomato plants that I grew myself under lights. They have been transitioned to a makeshift greenhouse to harden off. There are brown shots evident on the leaves (please see attached image). What shall I do? Thank you! Jim

Jim, thanks for the question.  

If the spots showed up after the transition this could be sun scald. The hardening off process may have been a little too fast.  If before the transition it could could be a burn from being too close to your grow lights.  According to some sources, plants too close to the light (especially LEDs) can cause the problem. Check out the following links:

I hope this helps.
