Cymbidium leaf tip dieback & pseudobulbs not growing

[varda.elentari]

Hello everyone,

Several months ago I repotted a cymbidium into fine/medium size pine bark sold at a pet store. I've potted other cymbidiums in the same bark after soaking it for several days and had no problems. Unfortunately this time I rushed and skipped this step and now the leaves are dying back at the tips. I water with tap water that has been left to stand for a few days and flush out the medium prodigiously but it hasn't helped so far. I don't want to repot the plant again so what else can I do? Is there something I could add to my tap water to help flush out whatever chemicals are in the medium? Or is it possible that the medium ph is off? Should I test it?

The pseudobulbs haven't grown at all during the summer despite the fact that I put the plant outside. When I bought the plant and repotted it I found that the tips of the roots growing from the baby pseudobulbs had died because of insufficient water. I understand that means those roots will no longer grow. Could it be that pseudobulbs stop growing once their roots stop growing? Or did I simply not give the plant enough sunlight?

I'm relatively new to cymbidium culture so any suggestions would be much appreciated. Thank you.
