Maybe compost tea would get the nutrients to your plant the quickest way.
If it is not a nutrient deficiency, maybe someone on the forum can tell what it is.
I did put a lot of compost on in the fall. I have another batch that's almost ready, I could put more. Be interesting to see if the newer leaves are OK. The only thing I can think of besides nutrient deficiency is some kind of cold/wind damage? The backyard is very windy at times, and we had several wild storms come thru late in the season.
