It's not about overthinking.. my first attempt at hydro is teaching me that with certain types of growing you have to get into certain routines. With any kind of hydro you have to check pH, EC/PPM, and water temp regularly. It's not hard or time consuming, and if there is an issue it is easy to correct and changes take hold quickly. Growing in any non soil medium requires attention to detail and diligence. If you get into good habits it becomes easy. Again, these aren't things I'm saying to be a jerk. If you spend 10 minutes every day just checking those 3 variables (pH ppm and water temp) your grow will be so much easier.
