I have been studying this issue I have had with 2 of my phragmipediums and I don't think I am quite getting my watering right. The short story is 2 of my phrags are showing yellowing leaves from the tips. I water with RO Water with a small amount of better gro fertilizer added at each watering. I use 20-14-13 (TDS never higher than 75). On occasion I supplement my water with dilute calcium nitrate and epsom salt (I never let the tds go above about 75). I flush weekly and the flush water shows pretty low on the TDS meter.
I have:
Phrag Green Hornet (Logifolium x Pearcei)-Just finished blooming and is producing 4 new growths (growing fast). All old growths have leaves where the tips are yellowing back. Repotted, showing lots of new root growth but leaves yellowing. In orchiata, large perlite charcoal, moss top dressing with a couple pieces of oyster shell. Watered about every other day. Always kept wet.
Phrag Jason Fisher-Seedling size. Growing quickly. In straight Orchiata. Watered every other day and always kept wet. Not showing any problems with the water I am using
Phrag Court Jester. Recently acquired, repotted into fresh orchiata, perlite and charcoal. Tip is turning yellow. Roots not strong.
Light: Window supplemented with LED. Cattleyas have grown and flowered under this setup.
