Cindy, as for the misting, I personally don't mist as I see NO benefit that comes from it. Unless of course you have orchids in terrariums.
Catts do like to dry out inbetween waterings, the questions is .... How long between the waterings is your plant dried out?
Do you use a BBQ wooden skewer as a guide?
At what strengh are you using the fertilizers?
While we're here, LOL, what kinda media do you have this 'chid in?
I think you plant is just being kept drier then it would like to be - fertilizers will only add to the damage.
whats the bbq skewers for? Billie
Mistking
Looking for a misting system? Look no further. Automated misting systems from MistKing are used by multitude of plant enthusiasts and are perfect for Orchids. Systems feature run dry pumps, ZipDrip valve, adjustable black nozzles, per second control! Automatically mist one growing shelf or a greenhouse full of Orchids.
Cattleyas like a full wet/dry cycle with watering and I have read that the higher the frequency of giving the plant this cycle the better it will thrive.
I would not cut bad looking leaves off of a cattleya plant as the plant is likely still using them.
I agree that your fertilizer is a bit strong and I would back off maybe using 1/4 strength every other watering.
