OK, with the MG soil, you have to consider that almost without exception, MG soil has added nutrients. So when you DO start feeding, keep that in mind. Seedlings wont need to be fed for at least a couple weeks after they start to take off, and the nutes in the soil are sometimes too much for them. In the future, avoid any added nutes in your soil unless you mix it yourself. I'd get the saran wrap off there and just be vigilant about keeping them MOIST not wet. The saran wrap could allow the air to stagnate and you'll end up with mold on the soil surface. Let the air circulate naturally. Peat pellets and a moisture dome make things SO much easier to control as the domes have adjustable vents on them.
I germ my seed in paper towels, the put the germed seed into a peat pellet where it will stay for at least a month under T-8s before I transplant them into their final homes. I put 1 seedling per pot under a few 400w lights to veg, then flower under 2 or 3 1K lights depending on how many I run, usually 72 at a time (4'x8' flood table, plants in 8" grow bags)
Just out of curiosity, why multiple seed in one pot? If you only want to grtow out a certain amount of plants, say 10, you'll need to germ at least 15 or 20 beans to ensure you get the amount of females you want. Putting multiple seed in one pot (to me at least) just creates some avoidable problems.
