I am growing some Kiwi from cuttings made last fall.  They are inside under a full spectrum 45 watt LED grow light.  There is a mix of homemade compost and Jiffy seed starter mix and local soil.  

The leaves are going yellow but the veins are still green. Would this be iron deficiency or sulfur?  What rate of application for a 6 inch pot?

I do have some SEA-90 if that would be okay to add to potted plants.  Any recommended rate of application if this is a good idea?

Not sure about Kiwi but in Citrus I would assume Iron deficiency or that the pH is interfering with Iron absorption.

I'd say Iron and probably manganese, just use a tea spoon full of the sea-90 per container to remedy the problem.
I would then add a second tsp. one month after the first treatment.

thank you Dr. Bryant Redhawk.  I have two more 50 lb bags of SEA-90 and will probably get some more in the next year to make sure I have enough for myself, my fruit trees and plants.
