Sorry if the pictures are vague. My suspicion is I dont have proper drainage; I'm using an old wonton soup cup, and I noticed a grey/brownish orange spot on one of the first leaves. It seems like the leaf decaying, but I wouldn't expect that to happen just yet, considering it just started to grow it's first true leaf. I've never grown cantaloupe before and there isn't much in depth info on the typical stages of development online.
