SEA berries Turning yellow

In the past month what am I see berries has turned yellow, it has new shoots coming up, and I have several others with leaves turning yellow? What is going on?

I thought it was over watering but I have space drip emitters that are turned on once a week, in fact, I went from every 4 days to once a week about 2 months ago.

Hi Edward,
Welcome to Permies!

I am not super familiar with the seaberry plants themselves, but here are a couple thoughts.

A few yellowing leaves just on the bottom would be fairly normal aging... but as many as I see there makes me think something else. Nutrient deficiency, incorrect watering (both too much and too little can cause this), perhaps stress from weather changes.

The nutrients you would probably need a soil test... but can you put your finger in the soil near the plants and see if it feels abnormally dry or abnormally wet? Also have their been any major swings in temperature lately say 90F one day and dropping to 45F at night or something like that?

Last month was 90-100's.... Nutrients with humic I cut back to once a month. Nutrients during summer I add no nitrogen.
My parents an hour north have seaberries and water every other day with dripline. I have similar soil, very sandy, and initially was doing every 5 days, deep water for 2 hours on dripline.

Soil moisure has been damp, to when top 6 inches feels dry I was setting my 5 day water.

Weather has been heavy ash and smoke.

Sandy soil in that kind of heat is really tricky, it drains fast enough that once a week might not be cutting it even with long run times. The smoke probably isn't helping either, plants really struggle with photosynthesis during heavy smoke events.

Could that color be from over watering?
