The Myeonggwanggae Mystery: The Return of Yellowing Leaves

You will rarely have fungal issues. Leaf problems are almost always due to falling short on growing conditions. Don't reach for fungicides; try and improve growing conditions.

Got it. I'm guess my liberal use of fertilizer is the cause of the issue. I'm also guessing this guy is just more sensitive than the others, as no other plant has had issues. No yellowing of leaves, no terminating of spikes, no sudden stopping of growth, at most one leave on a Vanda got a little burn from being in the hot afternoon sun, but other than that everything seems fine.

I'll flush out the media with distilled water over the next few weeks and see how it fairs. I'll also be more reserved with fertilizing than I have been.
