My soil is slightly alkaline, it was a little above 7 now I think its sitting just under it. That points to more of a zinc deficiency but I'm not really seeing white leaf tips. Iron deficiency would be my next guess but its hard to say. Yellowing only occurs in upper leaves between veins more toward the edge/tip of the leaf than the base of it.

Only leaves at top experience this, new leaves closer to the ground are fully green. Sorry for lack of focus on pictures but hopefully you can make it out. Any ideas would really be appreciated. This really is just a mild case too as most of the leaves are green and yellowing ones are only very slightly yellow. Still would like to get a handle on this though.
