Blc. Hawaiian Leopard growing question

[silken]

I received a good sized division of Blc. Hawaiian Leopard. It very quickly put up 3 new growths this summer not long after I got it and it had been newly divided at the time. I had it under lights with several other cattleyas. I use two 4 ft. T12 bulbs and 2 4 ft. T5 bulbs mounted on the outer edges of the T12 canopy. The 3 new growths seem to have all quit growing when they were about 2 inches tall and all seem to be a dark green with reddish tinge to them. Is this common with this plant's new growths or is it getting too much light? That would be my thought although most of my cattleya's do fine under these lights. Also the mature leaves are not being tinged red. I did try moving it to less light for a month or so and there is still no change-they just seem stalled. I don't think they have put out much for roots either and I am worried that they will die on me.
