Eggplant with drying leaves

I'm growing eggplant for the first time (Ping Tung and Nagasaki) and everything went well until I notices that some larger leaves have dry spots on them. The sports start as thinning of the surface of the leaf, than dry. I keep my seedlings inside, at 20-25 C (68-77 F), under 6500K LEDs. I've been watering with a liquid fertilizer once a week, as they are in peat moss substrate. The tomato and chili seedlings kept at the same place are spotless. I took them all out in the sun for 15 minutes two days ago. Does anybody know what's the problem?

I've got the same problem under LED lights. The ones under the fluorescent are okay.

I've just realized it's just on Ping Tung. Nagasaki is fine, as are tomatoes and chilies. I've raised the bulbs as much as possible.

Led lights accellerate nutrient uptake. That is probably a calcium/magnesium deficiency. You can fertilize more, dim the light if it has a dimmer, or just raise the light to be farther from the plants.

Mine are Ping Tung too. I'll move them to the fluorescents and bring some peppers to the LEDs.
