So im considering changing from tap water which is in the ppm range of 400, classes as "hard water" in my area, to RO water. It's only .25p a litre and I know in Rockwool it might be beneficial to do so.
Is this ok to do halfway through a grow? Are there any issues/challenges I might encounter?
Also, I have cal/mag and wondered at what rate of PPM's should I add it. Do I add 400ppm cal mag and continue with my normal nute regimen?
Im using floranova grow and bloom at the moment. Thanks for the help in advance.
