Don't think they should be deficient in anything yet, they're in new Ocean Forest soil and only on day 11 of veg, no way they used up what's in the soil yet.
More details in my grow diary comment.
This is damage caused by the leaves hitting either the edge of the pot or the soil surface when the fan blows on them and generally at night when the leaves are lowered. Nothing much to be concerned over.
Filling your pots right up to the top would give more room for root growth.
Hope this helps,..............
