OK nutrients generally don't give your plants anything except maybe superthrive the first 3 weeks or so. After that it gets complicated... If you can find something caleed bat guano then great use it while in vegetative stage. If not thenyou need to finda a fertilizer with low k value (read on the back N-P-K then a series of numbers for example 8-2-0 which is good for veg). Using nutrients while flowering I am not too sure think you need everything like 10-15-12 or something anything in that range. And rememberr to never trust what they tell you on the instructions always use half or less of the recommended dosage.
