I think your blackberry looks fine. The blueberry is experiencing chlorosis, which being blueberry I suspect is from an iron deficiency. Blueberries need iron, moreso than most other edibles. Blueberries like a soil with an acidic pH, 5.5 is a safe number to target. Iron becomes less available as a soils pH gets less acidic, or goes up closer to neutral. Adding amendments to acidify a soil takes time for it to work, sometimes a year or more. What kind of soil is it planted in?
The container is mostly peat moss with compost and worm castings and mulched with pine needles. I think the water though is very alkaline and I dont know if I made it worse with the fertilizer. I'm getting some test strips soon to test the ph. Can I use vinegar to acidify my water? It doesnt rain much here. How can I lower the ph?
About the change of seasons for blackberry, yes its almost fall or at least supposed to be but temps are just getting hotter this year no sign on it cooling down.
