I really like the variety of Haworthia you have Tarev. The reddish color appeals to me on your H. reinwardtii.
Do you have any idea what is wrong with the last Haworthia photo you posted?
I moved mine out of the greenhouse tonight. I am running late and some didn't look too perky. Perhaps too hot and too dry in there. I need to remove some from the soil and see how the roots look.
