I do every other watering with nutes but some people do it less or more it depends on your plants and if they like a heavy feed. A friend grows his with only one heavy feed every 2 weeks but hes outdoors in the ground. its all about watching your plants and dialing in the right amounts and times to feed for that specific phenotype. if your afraid of overfeeding get a soil with lots of coco or pearlite so it drains well, i recommend foxfarms ocean forest it can grow you some dank without much effort. I'd go a step further with a cloth pot (can make your own) so your soil is nice and aerated and you can water pretty much every day. Dont feel bad everyone had to learn at sometime. My first 2 grows ended up in the trash first to PM then to root fungus but i learned my leasons and haven't had those issues again.
