[compost_tea] Potato Nutrients for Optimization



Hello All,
 
I just got back the results from a nutrient analysis of potato leaves from our compost tea potato trial.  The results indicate that the potato plants are low in K, Mg, Zn, and B.  This also reflects our soil analysis.  Can anyone suggest a good way to increase these nutrients via compost tea.  Has anyone ever put sulpomag into their tea brewer?  Are there any products good for tea that would have these nutrients in it?  
 
Note: We did one representative sampling of each treatment (CT, nutrients without compost, and no spray control) and had the potato leaves analyzed (ICP).  The nitrogen levals were higher in the CT treatment 4.08%, lower in the no spray control 3.89%, and lowest in the nutrient control 3.73%.   Rember this was only one sampling, but something seems to be making the nitrogen more available in the compost tea treatment.    
 
Hope all is well,
