Leaf blotch

arrrrrgh

General post from chad

I have honeysuckle which has been thriving for the last two years since planting. It was growing fast before i went on holiday two weeks ago. I did however give a further feed before i went away meaning it had a feed two weeks running of miracle grow which much improved the speed of growth by feeding once fortnightly.
Upon my return i was horrified to see most of the leaves had died off and wish to know if any advice can be given to me. I have included a couple of pics which may lead to the solving of my problem.
