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?
