hey dude, i have the exact same problem, and so far, i have had no luck figuring out why my stuff does that either, i dont think its a calcium def just cause the ferts i use have calcium chloride i think it is, not sure, but thats one of the main ingredeints, so i really dont know. Were do u have it, like whats around the area, (pests, animals, light, water) are they in pots or grounded, have u had this prob before ? I have had it the past 2 years. I tried using a fungicide called blue lightning but no effects i dont think so dont just put it off as not a mold, i still beleive it could be a mold im not sure, ANyways, try talking to a garden specialist about some fungicides and its very possible well most likely a fert issue so go out and buy something like silica blast for an extra calcium boost. anyways keep us posted with ur progress,
