that picture isn't cannabis either. it's just some weedspecies that happens to have ruderalis in the name(like there are tonnes of species called sativa too). it has a completely different genus-name in front.
kalyseeds I've heard of before, and I think he's just working with ducksfootcrosses.
kalyseeds claims it's a hop-cannabis hybrid. but I don't believe that story. the details just don't fit, and it's too unlikely to be true.
especially considering all the pictures of kalyseeds' plants I've seen look exactly like the webbed leaves you get from duckfoot.
for example that picture on seedfinder looks exactly like the leaves of some of my plants this year. those plants were a duckfootcross, and I put them on flowering shedule to sex, then revegged. the slight revegging symotoms combined with webbed leaves produced mostly single-bladed leaves and some with one point to the side like a thumb.
some examples:
young plant before sexing(so just webbed leaves, no revegging)
and later, a while after sexing, they, especially one plant, kept pushing out singlebladed leaves for quiet a while(but no smooth edges or other worse revegging symptoms)
