your plants look fine to me.
calcium is characterized by distortion or clawing of the leaf(downward usually) due to the midrib and the leaf margin growing at different rates. one single leaf showing this is not indicitive of a calcium deficiency, as insect damage can make similar looking damage. so can burning from HPS MH lighting in my experience.
chronic calcium deficiency will make the entire leaf gnarled looking and clawed down usually, where as a new deficiency will have this only at the margins.
FWIW ive had plants that exhibited what looked like calcium defficiency-like gnarling due to heat stress only.
these stressed plants however had normal green colored leaves, and not mottled or chlororic in anyway.
that slight uniform upward cupping of the leaf margin you are seeing is normal in my experience. the lighter green color of the leaves is normal for new tender growth, especially with non annums in my experience anyway.
calcium problems, as all immobile deficiencies will show at the top, on all new growth.
