I went to water this morning and some of my fan leaves, 3 or 4, are curling under and have black spots. I pulled one off and it was dry and harder. I am in soil in my 5th week of flower outdoors. I "imagine" it is because it I have never checked my soil... only what is going into my soil. I am going to buy a kit this morning and test my soil but am uncertain how to "flush" in soil. Do I just drip water through it..? I am using hydro international
