Kevin,
Welcome to the "How to make a plant look sick" club. I think most of us if we will admit it, has over fed something. I killed and I mean killed a few by trying mixtures that someone online said was great. I just can not do that. I am one of these people who needs to buy it already mixed. I love Miracle Grow for that. I usually research the new plants carefully regarding how much do they like to be fertilized. One thing people do not think about is the contents of any potting soil they may use. Some already has certain minerals, etc. in it and then if you feed on top of that. You get beautiful brown leaves just like you have.
I am reading your post regarding weather. Do not get me started on the weather. We have had the worst Winter and Spring (there was very little) , now we are fighting the 90 deg. heat again.
I am too old for this. I like the old fashion Spring, Summer Fall and Winter. No sudden changes, not too much rain. My greenhouse is full of cuttings and all I do is water. They just may not dry out. The temp in there today got as high as 100 deg.
