Are your clones rooted? how long after you transplanted did this show up? This soil is organic and there is almost no way that it is burning your plants that quickly. Yes it does have organic amendments but like all other organics, they need to be broken down by bacteria and fungi to become availible to the plants. There is absolutly no ammonia or other chemical nutrient added to this soil, it is totally organic.
Which means that the problem is with the clone and its growing enviroment rather then the medium. I would say you are either other watering, underwatering or the cutting was not rooted, or the pheno just stinks, which it is suppose to. You are growing sour diesel, which is a very pungent smelling strain that smells like skunky diesel fuel, so I can definiatly see that being confused with an ammonia type smell. I find that very pungent skunks smell of ammonia anyways, almost like urine, but cat urine. That is what we in the MJ world define as dank, you always hear things like fruity, hashy, skunky and dank used to describe different strains smells.
I would suggest you to actually try and find the source of the smell, because i am pretty sure it is not coming from your 100% organic mix.
