Okay so I'm so damn close to starting my first grow but I can't get this dwc nutrient thing down. I'm really confused based on the chart they gave me at the store on how to monitor what nutrients to give them. I understand it is good to change the whole dwc bucket every 7-10 days and replace nutrients in a specific order to the water ( my water is 134 ppm). I'm confused on how much to give them and what to do to the water/nutrient mix during those 7-10 days. Do I just leave it be and when the water goes down in my buckets just top with water? Or do I need to add more nutrients in between the 7-10 days? If that is the case, when should I be topping off with more water. Also is this a good chart to go by for my grows? I'm using rapid start, flor plus, and flora series 3 part. Can I just modify the chart for example If I buy a lowryder #2 which is ready in 9 weeks from seed can I follow the exact chart but during week 9 start my flush unlike the chart which says week 12? Here is the chart! Thanks a lot!
