There is always that ONE plant

[Dusty Ol' Man]

For the past year or so I have been slowly acquiring mini catt hybrids. I have made improvements to my space, lighting, and conditions that have allowed be to bloom plants needing brighter light. My full size hybrids are doing well, and five out of six of my minis seem to be growing well with new pseudobulbs, roots, and healthy leaves. I should mention that all of these plants are in semi hydro, and receive the same general care.
But there is this one plant that, no matter what I do, how diligent I am with its watering, just will not grow. This is Rlc Sandra’s Beau (Rlc Little Toshie x C Beaufort). This was the first mini catt I bought. It came bare root and seemed fine when I received it, but soon after potting it began to lose roots and started floundering. I thought it was my care that was to blame and quickly pulled it from the pot and put it in ICU (sphag n bag). I used Kelpak as recommended and kept it warm and shaded. After several months it produced a new root so I potted it back up in semi hydro to watch the magic. It grew two new pseudobulbs and some roots to go with them. Then it started to go backward again. The new roots would get just so long before stalling and beginning to wither. Now the newest growth is showing signs of dehydration and its root has stopped progressing.
Conditions are: temps 85/68 degrees F, bright light the same as the ones that are doing well, humidity 55 to 75%. There are fans moving a good amount of air throughout the tent.
I’m at a loss and would like some advice on a direction to try to make this plant happy.

Personally, I don’t discern anything obvious, based upon the described conditions and the fact that the other plants are doing fine.

Sometimes we just get “runts” that struggle.

I hope someone else has a better idea.

I agree with Ray. Over the years, I have found that, for whatever reason, some plants (orchids and non-orchids) will not thrive whatever one does. Most of the time it is genetics but, sometimes...? When I worked in a nursery potting up cuttings, we were taught to always put three per pot as some would not root (even though they were from the same plant, soaked in the same vat of rooting hormone for the same amount of time, same size and given the same conditions). Why one thrives and one does not is a mystery that many plant experts still do not quite understand.

I don’t grow these, but I agree that it’s seems like you have a genetic dud on your hands.

I sometimes get one, for I have to conclude, "That one just doesn't like me". And try not to take it personally. Nobody bats 1.000 .

Sc. Beaufort doesn't like heat. Try keeping it cooler.

Also, since this is a root problem, look for bush snails.

I dont know but I have that one plant too. When I buy plants I generally observe an increase in vigor. My dud plant is no exception it grew a beautiful bulb much larger than all the rest, then it stopped stagnated, slowly drying out and taking three years to die. I may give it away. It has an FCC so it's gotta be me...

[Roberta]

If it's an FCC it's a mericlone most likely. So has to go through the same growing process as a seed-grown plant. I suspect that all individuals coming out of the same test tube are not created equal. (If it's a division of an FCC plant, different story)

[Louis_W]

Actually I just looked and it's x self so all bets are off. I'm sure it's still my fault

[Roberta]

Nawww... don't take it personally.
