My first few pens as a beginner!

Am I the problem or is it my TWSBI Eco

My hoyas’ (obovata and pubicalyx) leaves stay bendy/pliable even after I water them. Should I water them more? Or just leave them to adjust?

Hi! Hoya newbie here. Just wanted to ask what the best indicator is for knowing when to water hoyas? Some sources say to water when the potting medium is dry, but some say to water when the leaves are soft/bendy or wrinkly. Thoughts?

Hi! Any tips on this hoya obovata? Entire stem is rigid and woody, stands by itself. Leaves are also bendy and green. Roots look fine, no rot or anything, though a little short. Will there be any new growth even with the woody stem?
