Apologies for reviving old thread, but seemed better than starting another querying same;

 

I've looked all over for good Cal-Mag supplement. Growguru don't stock whatever this was anymore :(  Hortishop only have the calcium nitrate base which is really high in N, as you mentioned in this old post.

 

Is there anything else on the SA market? 

 

Currently worried af at combining Epsom salts (for the Mg) with nutes and/or chelated calcium, and just about anything really, as it precipitates as gypsum (right?) so I just foliar feed epsom when needed for Mg.

 

Really need a source of Mg!

What are you, and peeps, using to supplement Ca and Mg when required? Calcium nitrate base hortishop type and compensating for the extra N?

 

I haven't been growing hydro for a while now but will be next month. Right now I see Horti's calmag nitrate as the only option for buffering
