Signs of an issue using Coco Coir
I noticed two leaves (on the same branch) are showing signs of something. It looks like it may be a deficiency of some sort but I am not sure. I tested my EC and the run-off EC was off the charts >7000. I am growing in Coco and I am new to testing EC. Need advise.

Spraying the leaves
While I was checking my plant I saw these “black stains” like the plant is “half-bitten/scorched”.Is it possible to burn my leaves and create this effect after spraying them with nutes. Blacks spots were created today after I sprayed them and there were drops on leaves for hours

Nutrient burnt leave removal question.
Should I remove all the burnt leaves? Worst ones are 25% burnt. Some just speckled throughout. Do the flowers still need exposure to the sun? Or will the leaves exposed to sunlight keep the buds growing? Can cutting the burnt leaves cause enough stress to hermie or stunt growth?

Spotted Leaves
My ladies looked good until recently, it has been very warm the last few days. Then they began to let their leaves hang down (didn't get enough water) and gradually turned yellow, now they are getting spots. This is my first grow and I am not sure what it could be.
