I’ve got an RO filter and am running an RDWC system with ionic soft water hydro nutrients.
How much cal mag do I put in? On the bottle it has 2 measurements. As far as I can tell it say 1ml/1L to get a plant back on track and 1ml/2L to keep them sweet. This can’t mean much though as it’s not saying what nutrients to use it with and what background EC you are working from.
has anyone got any experience?
For the first feed I’ve gone with 1ml/2L but that was only last night.
