Hi, im a new grower and the last 2-3 months Ive started my first grow und read a lot about cannabis but some basic questions I couldnt find the answers to. 1. My tap water has a very bad cal/mag ratio 11:1 (70mg/l cal and 6mg/l mag) should I add some magnesium to get a 3:1 ratio ? AND should I mix it 1:1 with brita filtered water to reduce the micronutrients and add magnesium? Because Im not sure how much cal and magnesium the plants needs. 2. When im using nutes in my water and the ppm of my solution is higher than my drain is it a sign of underfeeding the plants and I should give them more nutes next time? and if that is the case can I eliminate that i have a lock when the drain is lower than my nutes solution? 3. Some people say when using nutes the pots shouldnt dry out before watering again becuase of the salts that can build up in the soil but others say the opposite. So what is true? Thanks!
