My gongora leucochila is struggling

[ALToronto]

I have it in an east-facing window, so only morning sunshine. The potting mix (CHC, lava rock, charcoal, perlite, sphag) is slightly moist most of the time. I don't really let it dry out. I'm watering with weak K-lite and occasional seaweed extract.

My problem: it starts new growths, but within a couple of weeks, these growths wither and die, long before reaching maturity. It has also lost all its mature leaves. The new growths start dying from the outside in - first the outermost leaves turn papery brown, then this condition progresses inward in each new growth. Roots, however, seem to be reasonably healthy.

Any help would be much appreciated.

What are your temps? And type of air movement goes on in your grow space?

The window is open most of the time, and temps have been between 18 - 30 degrees (66 - 87F). Is it a cool growing plant?

I had mine in Hawaii and it got watered every day, but had very strong trade winds blowing every day. It also got pretty bright light (mid Cattleya light) and grew like a weed. They also like a lot of fertilizer when actively growing. Here's an old thread of mine that might help: http://www.orchidboard.com/community...eucochila.html
