One plant at each end of the EB, let say the far left corner for one and the far right corner for the other. The fertilizer on the far opposite side against the rim opposite the plants. Two reasons:
1) using chemical fertilizer the roots will be protected from burning.
2) Organic fertilizer, three cups instead of two, will not burn but in both cases will make the root stretch for their food making them stronger.

I have been amazed at the size of my roots at the end of the season when I have to clean out my EBs and have shown pictures to prove the results.
