@Bill284 he's in rural south America. I pointed him to his local feed store they've likely got everything he needs.
@kikikopa - Its not heat. Plants take a while to show signs of issues a week or more and also take a week or more to recover.
You soil mix is missing some important amendments like Calcium - this is your issue and why your leaves are dying off. Its not the end of the world. The problem with low Calcium in your soil mix can be resolved easily. EWC has Ca in it. You can make a slurry of EWC an water in. You will have to do that frequently.
I asked about your water filtration for a reason. What type of filter are you using to filter out chlorine?
