hmmm ... from the photo, it looks like ya got algae growing ... never seen that in fresh soil before ... are you using aquarium water, or some other 'dirty' water source ? ... that's peculiar ... I wouldn't freak over it, yet ... I think I'd just try watering a couple times with regular, chlorinated tap water, see if that doesn't clear it up ... (chlorine does NOT hurt your plants, but it does kill some beneficial organisms in the soil, won't hurt to try it a few times, in this case) ... also, be sure you're not over-watering ... :wtf:
