Phal blooming question
I'm fairly new to all of this, have only been growing for three or four
years, under lights. I've noticed that while my phals bloom each year,
with each year the spikes are shorter and the blooms less spectacular. I
grow under fluors at about 2000 ftc's and use Dynagrow/Blm, 1/4
tsp/gallon each week. Any thoughts as to why I seem to be left with a
bunch of shrinking phals? Thanks.
