Yesterday I noticed that they were getting some type of deficiency. So I did a res change and upped the nutrients. Originally I was thinking that it was a calcium deficiency, but now I'm not sure because they are turning grey. Root growth seems to be stunted also. Any advise on what's going on will be greatly appreciated. :hippy:
