What kind of lighting? With led it seems some people need more cal mag. With traditional lighting hps or cmh style lighting most are good. I’ve never needed it but I always use my well water which supplies a little extra anyways.Do I need to add Calmag when using mega crop with RODI? I just made the switch, always used it with any other nutrients.
LED, I’ll use the recommended amount and see how it goes. Thanks manWhat kind of lighting? With led it seems some people need more cal mag. With traditional lighting hps or cmh style lighting most are good. I’ve never needed it but I always use my well water which supplies a little extra anyways.
Sounds goodI don't think it will hurt them. Megacrop works very well with stable PH with tap water so RO with cal mag should be about the same
Thanks!It's got calcium nitrate, magnesium nitrate, and magnesium sulfate as some of it's ingredients. Even with RO water you shouldn't need additional calcium or magnesium. Fertilizers that use calcium nitrate as their main source of nitrogen should provide all the calcium you need. Calcium nitrate is the first ingredient in MegaCrop.
