Weak feeding with almost every watering, preferably in a ratio that is good for tomatoes (2-1-3 would be a good all around). Since the EB is a closed system, the farther away you stray, the more certain stuff will accumulate (in your case that would be P). Should still be ok I guess, if you plan to change your medium every year.
Now, how much fertilizer per liter? If we look at instructions, they say 2 cups for 1 container. That's a pretty hefty amount, at lest 500g. For my pruned to one stem plants, I use about 500l for 2 plants per season (very guesstimate). So let's say you use 1000.
That would mean you should add 0.5g per liter at every watering.
