To my mind (and I could be wrong) wouldnt smaller leaves be an indicator of
prolonged adequate light reception, remaining short of the burning point???

Cheers

Hello Everyone,
I've been recently having some problems with some of my orchids, their
plant growth to be specific, they are growing smaller leaves, and I
know they're getting plenty of light because they're in a west window
with 2 40 watt 4 ft fixtures.
I water with distilled water, some of my plants are in bark, some of
them are in moss...I noticed the ones in moss and one in bark are only
having this problem...
I water with distilled water at 5.6-6.1....should the water be more
alcalinic to offset the acidity of the potting medium?
The potting medium despite being sphag is around 5.5
