I used it across the board for all my plants except the bromeliads, including phals, dens, catts, oncidiums, cymbidiums, etc. The mounts all did fine, and a few random of the other varieties turned new tips black. But all the vandas lost the new tips.

It was not likely the fertilizer that damaged the Vanda roots. More likely they didn't get enough water. Commercial growers in Florida have used 2-3 tablespoons / 30-45ml of 20-20-20 fertilizer powder per gallon / 3.78 liters water to fertilizer Vandas, including seedlings.
