Don't get me wrong reading all you can is great. But it also can make you think to much and have you constantly wanting to change stuff in your grow, and before you know it you can be moving backwards and not learning because you're trying so many different things. For beginners I maybe recommend one topping and then just worry about keeping the plant healthy and happy. My goal is for the plants to be perky at all times. Only time they start to droop is when it's about time for the lights to go out and they start to go to sleep.
