A bit of a mystery!

[vanda_obsession]

So the first 4 pictures are of my kasem's delight black, and the last pics are of my other two vandas that are healthy (minus the few scars and the sunburn spots from 2 summers ago)

This kasem is a newer vanda to me. I wanted the roberts delight black but my grower had this one and sold it to me. For some reason though it is showing signs of dehydration (however I water it everyday) and I keep a humidifier running all the time to help with our dry air during the winter. My other two vandas are still (slowly) growing new roots and the biggest one has a spike nubbin growing too... This kasem's has almost stunted itself, it looks a little rough and I really don't know why. It gets watered alot and it's always seems to look dehydrated (shrivels on leaves, roots cracking..) It has these tiny black spots on it and that to me seems to be the only reasoning of what would be wrong with it? My other two are happy growers and this one does not seem to be showing me the love! Please help

Sunlight here is a little rough this time of year, it typically dips down below the apt building across from us, but I try to hang them in the only two window options I have to get sunshine... When it gets warm enough I put them outside in the mornings to be able to get some morning sun, which by the the afternoon which will burn them, they are shaded some by the trees, before the later day sun rolls around to give them some more light. Watering is done frequent. I fertilize them with jacks classic 20-20-20 weakly but on a daily basis (they get the epson salt 'flush' once a month with my sprayer) and I use a bloom booster once a month (from the same company) all as directed by my grower (which I throughly have trusted for 10+ years in their advice)

How do you water the vandas? This one may need a longer soaking than the others. Or, maybe it is less tolerant of sun/heat. Hopefully a vanda expert will come along.

I water / spray daily in summer fertilize in three days as they are in hanging position without mix.In cooler weathers I defer watering unless in full/ partial sun. You will no doubt get more input from regular hobbyist.

I have a species one that is tempermental. Ever since I took it out of the box it arrived in its wilty looking but I started soaking it in a tub of water while I water all the other chids and its happy as pie then it wilts a bit again and I soak it again for a couple hrs lol. Its box mates don't do this. Just this one. But it like long soaks. I soak the box mate Vandas as well but some times I do this one longer and more frequently.
Seems to keep it happy by soaking and I add fert to the water also every other soak. I dump the warere after in a ficus tree which is very happy these days lol

It's just so weird that this one is giving me a hard time... my other guys are all so dang happy... I use a 2 gallon pump sprayer and I water them till the water runs off them after they cant absorb anymore. I put them in the bathroom at night for the humidity that gathers when we get our showers. I guess I'm going to have resort to taking bubble baths with this one! stubborn thing!! Hopefully it won't drink my wine!
