There are some color developments on the watermelon-lesliei. You see, two months ago the islands on its surface were green-yellow-ish - now they are yellow-orange, even partly red-ish. For me it is interesting because watching the plants throughout a year it looks like lithops tend to lose warm yellow-red pigments first when they grow becoming pale and more green in the fall, don't you think? Seems to be the other way around for this plant. Maybe something's wrong with it (checked the roots recently, they were ok). I'll keep you updated.
