Cymbidium won’t grow

[Girl_With_An_Orchid]

Hi all! I need some help with my Cyms. They grow super slow and stop at around 6-8 inches long for the leaves. The leaves also don’t usually last very long. When I first got the plant (it has been split into two) there were tons of leaves and clusters that were easily twice that with really big healthy bulbs. I haven’t been able to get any pseudoblubs of any decent size either.

They are in separate plastic pots but the same decorative pot so the get the same everything when it comes to water and environment. They are kept wet/ moist, get fed miracle gro tomato food every few watering, and receive mostly full sun for several hours a day. They were outside getting really good light but are now inside with slightly less, but still bright light. The roots seem to be doing well, from what I can see through their pots. A definite improvement from when they were potted last year. I’m in zone 7 so they don’t winter outside. I currently have some leaves growing which started over a month ago, I think. I’ve attached pictures. What should I be doing differently so that they grow better?


(The twine is there because they were previously outside in a very windy place and the moss kept flying away. They aren’t there anymore because it was way to much light. I just never got rid of the twine.)
