today i pulled out the two biggest leaves and removed the flowering stems from my most successful phal due to crown rot. my others are not growing, one has a new leaf that is thin straight and very floppy. another has 3 stub roots and dark green leaves however much sun it gets. my mini phal has signs of root rot. i think i have one good phal, which is growing on a rubber plant
my den is out of control, my paphs are doing great, my vanda cant stop making fat green roots, my miltonia is on its 2nd loads of flowers and my onc has many new growths and roots.
even my pleione is growing nicely, i dont see where i am going wrong

i have been growing them like paphs but slightly warmer with abit more light, yet they refuse to grow, and just slowly rot. any secret tips?
