The one variety that displayed like that last year was Cosmonaut Volkov and I took the puckering on the leaves to be mag deficiency. Most noticeable in the oldest growth, but still vaguely visible on higher leaf sets. These plants carried heavy foliage were the first to come under a fruit load, I took it as a bellwether and resumed full strength nutrient levels on all plants after having backed off during a hot spell fearing evaporation was increasing fertilizer build-up.
I'm not sure my diagnosis was right, but the plants grew through it and got healthier, going on to be excellent producers.
