I would see how the plants respond after a 5-7 days. If the Cattleya is dark green, turn it up a little. Keep going until the Cattleya is light green, veering to yellowish. Orchids move slowly, so don't be in a rush.
And remember the Oncidium doesn't need as much light as the others.

Thanks I was trying to scootch the oncidium far away, but it might still be too close to the bright light. Maybe I should move it over to the other will with the phalaenopsis
