Dendrobium Spectabile yellow leaves on young pseudobulbs..

[jasongomez0]

Hi everyone, I'm having a problem with a new dendrobium spectabile (shorty) i recently purchased. 'shorty' being it has much smaller canes than normal. currently in a 4" pot. The media is a bit broken down, but not in terrible shape. two leaves started yellowing, slowly, first one then another. the yellow is on the smallest canes. maybe the pot is too crowded?
Other than that, i recently moved the plant outdoors, into a position with dappled light most of the day, with a period of full sun later in the day, which the plant is generally responding well to. Could the yellowing of the leaves be a sign of this change? from a windowsill to outside?
I'm in southern california, not far from the coast, so the weather is warm and great air circulation. the plant is elevated on a rack

OR, am i drowning the poor thing?

looks like new growth is green and the yellowing is just on senescent early (old) growth?

Yes, that's what I think...it's old growth about to go.

Agree looks like just an older leaf ready to go..and since you just put it outside, the plant is acclimating.

A big THANK YOU to everyone who said the yellowing was simply old growths fading away. After thinking more about it, the leaves that were yellowing were appearing on really old, small, shrilled, pseudobulbs, possibly the first growths on the plant. So yes, the answer is quite clear. I believe 'daddydoall' was first to recognize this.
