Hi all just wanted to ask some advice on mixing nutrients for an RDWC system & this will be my first grow using this system & also growing indoors or with hydro at all.
I plan on using Advanced Nutrients Grow Micro Bloom (ph perfect) as a base & anything else I add will be AN as well.
I will be using 4 x 27 litre pots & a 50L res + a 100L/min air pump with 2 x 50mm stones in each pot + 4 stones in the main res.
I have a couple of questions since I haven’t been able to find a lot of info on RDWC systems when I search.
Do I add most of the water to the system then mix nutes in a separate bucket & add all at once or can I add all the nutes 1 by 1 to the running system without causing any shock to the plants?
How often should I change out the entire solution? I have read contradictions of change every week or every 2 weeks or don’t change until switching to flower.
