Propagation: Leggy seedling help, 2 by ambuzz

Hi gardeners! I have started plants from seed before, but I have never had this issue. These seedlings are only a few days old, but they are already looking like they are reaching for the light! Funny part is - they are very close to the light, as you can hopefully tell in the pics.

Should I attempt to cut off the tops of the cups? Any other suggestions would be greatly appreciated!

The seedlings are veggies (red and yellow onion, broccoli, Brussels sprouts, cauliflower, beets, etc..) oh, and melon.

Many thanks!
