no it is not overkill but it is a lot of light, you would like to keep close monitor of it like they say cause if would grow very fast, is it a hortilux blue or hortilux metal halide?
i have also found out that in veg stage when the humidity is higher like at 60-70 they tend to grow way faster then at 50-60 humidity so try that out also oscillating fan is a must in the veg room
