Claude, my guess - if the plants are actively growing - is that it's
perfectly natural.

Hello everyone!

Ever since I optimized my growing condition by adding an ultrasonic
humidifier and a fan running 24 hours a day, maintaining an average of 26
C
daytime and a RH of 70 %, I noticed today that some of my phal are getting
rid of their oldest leaf !
My question is: Is this something wrong or it`s because the growth rate is
stimulated by the new optimized condition?

Thanks

Claude
