Phrag Giganteum with leaf tip die-back
Hi...I recently received a Phragmipedium Giganteum. There are two fans, one with 6 leaves, in spike, on its second bloom. The other fan is newer, has two leaves. Both leaves on this newer fan are a little on the yellow side, and one has a good start of die-back from the tip. I have only used distilled water to water it, and it is potted in sphagnum.
I'm not sure what to do since all it's gotten is distilled water. I'm hesitant to unpot it and really check its roots out since its in bloom and there appears to be possibly a third bloom on the way.
Advice?
