175???
I saw a florist window today - had all these big white phals in a mountain of moss.
makes it look expensive...
wonder if you could check the roots of other stuff he has for sale-
anyway most likely those 175 $ phals are form the same 2 or 3 nurseries that sell to Home Depot etc...
like
Kerry's
or costafarms...
i wonder why they put the Dendrobium in wood or coconut and the Phals in moss...
so you can replace for under $20... maybe less.
anyway I am a novice myself - I got one DTPS / phal form Ikea - had beautiful blooms but the roots were badly damaged - tried to save it but no way. had so many blooms more than everything on sale tehre.
now i tend to buy either species from ebay [4/6 bucks each - got equestris, mannii, bastianii from larry's orchids - 3 very ok - one had some root rot]...
so anyway I suggest you to buy some on sale for 1 or 2 dollars [usually no blooms]. or Trader Joe's or whatever big store - anyway as I said they most likely come from Costa farms and kerry's, whose labels state that it is ok to throw the plants away as they will grow more!!!
anyway from your first photo i got the impression that where you put the plant was a bit dark. and also
these florists always use huge pots that never dry up fast enough...
I also would suggest to get a Dendrobium - they seem less finnicky and way more resilient than Phalaenopsis. and if one cane dies tehre is always new growth, somehow they regenerate themselves more than Phalaenopsis.
