Is there organic calcium nitrate alternative?
« on: June 10, 2021, 04:30:28 pm »
I am new to Earthbox and greatly appreciate all of the Q/A and advise in the forum.  I used organic media, fertilizer, and dolomite when setting up my boxes.  I have 2 boxes with tomatoes and would like to be proactive with the 'snack' to prevent BER.  Is there any organic alternative to calcium nitrate?
