Fox Farms nutrient recommendations?

Hi Everyone,

Quick question. I am currently using Fox Farms nutrients for my grow. I am trying to follow their weekly feeding schedule, but I think I’m doing something wrong. Each week it gives you a list of what to add to the solution, but when I do my nute reading with my meter, it isn’t even close to what they’re saying the ppm should be. Should I be adding the weekly nutrients to my current solution, or change the solution and put in just what they recommend for that week? I’ve been changing the solution every week. Should I not be doing that? Plants look good but I’m thinking I could be getting more out of them! I know some of you will know the answer, thanks in advance for your help!
