Monnierara Millenium Magic - update!!

[TampaBear]

Hi everyone! Here's an update on the millennium magic I posted about earlier this summer (thanks for the advice). So I purchased this one back in April and it looks like it never went dormant and was already in full swing. It grew another growth and boy it got huge!! The leaves never got quite as large as the original pseudobulb... weird. Well the leaves of the original bulb are yellowing rapidly and a few have fallen. Everything I read makes me think it's doing its normal end of season slowdown. So does this mean I should start slowing down water and fertilizer or should I wait for the new growth to slowdown too? Dare I hope that a spike is on its way? Lol. I also have read that this type doesn't always go into full dormancy.
