Maybe that batch of potting soil was not very well mixed and contained pockets of peat. That really looks ph-y to me anyway.
Did you do the runoff test yet?
stinkyattic Reviewed by stinkyattic on . Nothing I Have Seen Before I have some dark spots on quite a few of my plants leaves, I have never seen this before. Can anyone enlighten me? I am guessing it would be some sort of nute problem, except I don't think any of my plants are suffering from anything other than this (check out my grow log thru my sig, i just posted new pics of my vegging plants). So anyways, here are some pics. Rating: 5
