More like severe nute burn or heat stress thinking. Probably first option but need loads more info how your growing.

Hi,
Firstly these are all grown side by side in 10L pots(Good Soil) With two suspended CFL Vegetation Lights above plants (One is 250w on the left, other is 125w both 6500K)
Now, they are growing in a Medium-ish Cupboard with Mylar reflective material surrounding all walls, The bulbs are about 4" to 4 1/2" away from the plants. The plants have been growing for nearly 2 months now and there is a osolating fan operating within this cupboard, The temperature fluctuates when the doors are shut(It does have someone living in the room ajacent to it) When the doors are open, you can expect a temperature between 24C and 26C, However, now this is the main problem, when the doors are shut the hot air in the room has nowhere to go(it does have a high ceiling, But no extraction fan atm to suck that hot air out.
Main problem Doors being Closed. If you look at the Plants yourself you will see most if not all leaves are vibrant and green with nothing odd, But I think some leave edges become exposed to this severe heat damage that happens only at night.
