hey poopster, your plants don't look that bad for being a month old, i have some about the same size. your leaves look nice.
i do have to agree with spicy, i think it may be a heat issue and possibly humidity. i still have many of my plants in their heated germination chamber, i keep a jar of water on the mat and pump in CO2(i put sugar, water and yeast into a sealed jug with a hose attached to a small air stone and it is in the jar of water. when i check my plants every morning, they are nice and wet and the humidity is dripping off the clear plastic dome. all i have is a cheap CFL 6500K bulb pointing at one side of the chamber.
may i asked what you are feeding the plants with, other than the epsom salts? like spicy said, we are well into the 2 page and i bet by the time i press post, we will be on the 3rd page, i may have missed your feeding cycle.
