Alien moonrocks outdoors

Planted them in front of pole beans. My plan is to incorporate autoflowers as part of a normal vegetable garden-I usually plant leeks here but how many leeks can one use? The soil is sandy, on the acidic side. I amended the soil with soil builder (Coast of Maine) garden soil, dolomitic lime, homemade compost and Plant tone (a little higher in nitrogen than tomato fertilizer).
