hmmmmm i find oncidium alliance to be a pain in the butt and slow to grow if they arent very well established. This plant you have only has 3 pseudobulbs and who knows what the roots look like. They do love that water tho, yet like to be dry to..I would have to agree with the fertilizer part. Less is better..and sometimes I give them 5-6 hours of sunlight with no problem, granted i dont live in florida anymore...hmmm.i dont know...like i said im not very good with them, but I dont kill them either,...haha....i wouldnt worry about the spots and leaf tips. That could be do to alot of different things. As long as it doesnt take over the whole leaf you should be fine. If it has some good roots tho and you keep up with the water, then you will see some plump bulbs and some new growth soon i bet
