Watering a newbies most common mistake. The best way I can explan is water by weight. When you put soil in your pots get a feel of the weight, set it down & pick it up to get a feel of dry weight. Now the 1st time you water you wiill also get a feel for that weight. When dry your plant will be lite, not so lite, not so thirsty. Happy learning frankrizzo!
