Hello, obviously you sprayed on your plant something that burns the hell out of it, as well as you burned it with too much ferts in the root zone. It's surely not deficiency. Now you need to spray your plant very well with distilled water, till all this bad stuff is washed off. Than you need to flush it properly with pH'ed water (with no nutrients). Give it a week to recover(or when one inch layer of soil is dry) . Next watering, put nutrients at 1/4 the recommended amount, and increase the nutrient concentration slowly with every watering.
Do foliar feed only if you have deficiency and your soil is too wet for watering, also make sure before spraying any nutrients, they are suitable for this purpose.
