SOIL Need help identifying this problem with these plants (first grow)

[Zink]

grown outdoors
Recent heatwave of 28-33 degrees celsius and a low of 20-25 for roughly 10-14 days
The leaves are yellowing and dieing off
i feed them Alaska fish farms fertilizer every 3rd watering at 3/4 strength which is 5 1 1
i dont think its nitrogen deficiency however i am not sure any ideas on what this could be?

Your pics dont work for me.

They don't work for me either, it looks like your pictures are loaded through gmail some how.
Whenever I upload pics on this site: I hit the camera Icon, then choose the upload button, then I upload the pics from the picture file on my computer.

I'm not really all that great with the tech stuff, but incase you are uploading a different way, maybe this will help.
It took me a couple months to figure out how to get the pictures from my camera, to computer, to this forum, Lol!
