Growth habit of Candy Sweet Icicle and White Oxheart

[Merediana]

I've always had some varieties that grow more sturdy, look more delicate or seem to be bigger/smaller over all than other varieties but this season I have noticed that Candy Sweet Icicle and White Oxheart look quite different than all the others, overall more flimsy with elongated leafs. Is that normal for these varieties?




Just as comparison some different seedlings that grew up under the same condition:


Is that normal?
