Hi mate, from what i see you've definitely over fed her. Leaves are showing signs of nutrient toxicity and burn. Your soil is far too dry, if the soil is coming away from the pot you've left it too long and will stress the plant. Your first course of action is to drench the soil in water till its flowing from bottom. Saturate the soil and maybe remove some of the excess nutrients. If you're using organic nutrients it is best to not fully dry out the soil as any beneficial bacteria will die off. I hope this helps, good luck...
