I'm using my soil for the 5th time. It consists of hp pro mix coco coir and coco loco. Have added coco coir and perilte each cycle with castings 1 cup per gallon. I use bonemeal 1 tsp per gallon this time coast of maine 6-2-0 8 percent calcium lobster meal 1tsp per gallon and epsom salt the same. Again around week 3 its starting I'm thinking nitrogen but not sure and these beans cost me alot. Old world genetics dj short blueberry.

Yellowing around the edges could mean a potassium deficiency. Do you have a soil test kit?

They aren't curling yet like a claw. Nothing is dead around the edges either. Just give it a couple days and make sure you don't overwater.

Looks like Iron deficiency. Try adding Cal/Mag, clip off the effected leaves and you should see a difference.
