A couple of Paphs in flower again. This is the easiest growing callosum I have encountered. It is even starting to clump. The Vanda M Pearman looks a bit wonky this time.

Wow! What a beautiful callosum. And the hybrid isnt too bad looking as well.
 
What brand, strength and frequency of fertilizer do you use?

The fertilisers I use are MAGAMP and Trio (CMB) Foliar. The MAGAMP fertiliser is a slow release fertiliser that simply attaches to my hose. So basically every time I water I attach the MAGAMP and it fertilises and waters at the same time. Too easy. MAGAMP contains high levels of Mg. On the downside it has high levels pf P although I can't say I have noticed a problem because of this.

MAGAMP doesn't have any Ca so I also regularly use Trio (CMB) Foliar which contains 16.8% Ca. It also has high N and Mg and little K. I regularly apply Trio (CMB) Foliar as a foliar fertiliser but also apply it to the potting mix every third application.

I apply the CMB at half the recommended concentration. I'm probably fertilising at a higher concentration than a lot of people on this forum.

I was under the impression that Ca was not well absorbed through the leaves.

I had heard that too, primarily through this forum. I know little compared to many on this forum but I would have thought a specialist agricultural fertiliser company would be aware of this if this was the case. Given their fertilisers are directed at a way more important and lucrative market than orchid growers, I would be amazed if the Ca from CMB is largely unavailable to the plant. The company strongly recommended me to apply it as a foliar spray as they said it was a far more efficient and immediate way for the plant to access the nutrients. I do apply it to the potting mix as well, so the plants can definitely access it through the roots.
 
Very nice callosum David. And well grown. Do you find find this clone easier than others you have? Parents?

'Shirley' x 'Dark'.

Way easier. It is a nice easy growing clone that flowers every year. All my other clones I have found really difficult. Funny as the guy I bought this plant off said he was really struggling with it. I have two clumps of this clone. It hads two growths when I got it which immediately fell apart. The plants are getting big enough now that I might start to see multiple spikes.
