My tip is to start out half dosage, to see how your plant react.
How big are your pots?
25-33% of the soil, is the "right" water amount.
Then it also depends on the stage of your plant. Seedling, Veg, flower?
When it comes to how often, your pot needs to dry out before you water again.
Stick the tip of your finger down 5cm, if its moist, wait.
Some say every 2 day, some 3 and 4. Someone even everyday.
Chose your style, but rather underwater than overwater!!
