First time grow

First of all, the best thing to do is to get to know your plans and your nutrients. I use advanced nutrients, sense of bloom sent to grow and multiple other items like overdrive, big bloom, voodoo and many more. I would recommend adding a microbial like Dynomyco works amazing for me. Always. Remember to start at about 1/5 of the recommended dose and do not feed more than once every 4 to 5 days. Best way to learn is to get in there and do it. Look at what your plant wants and remember it's good for it to be fed. Yet overfeeding is much worse than underfeed. If you have any questions let me know. I'd be happy to help. Also getting a pH and a TDS and EC will help cut out a lot of the guesswork. Just my two cents.
