Oldschool Blueberry vs. Newschool Blueberry outdoor

Nice sunny week, it got really hot again. I had to water a lot. 10-20 litres per plant per day. I spread some compost and a few additives around the plants. The blossoms come slowly. The Blueberry started first, two weeks later the Cupcake, and another week later the Pancake. I don't think that the flowers will be very big, probably I'll make Waterhash out of them in the end.
