It is a 19-19-19 that is meant to be dissolved in water and used as irrigation, not poured on the medium first. The outer coating of orchid roots - called "velamen" - acts like a sponge to rapidly absorb nutrient ions and hold onto them, as a defense against torrential rains stripping nutrition away. By pouring the concentrate on the medium first, the plants are absorbing it full strength.
If you are using it once a week, I would suggest no more than 1/4 ml/L.
Ohh ok I see, I’ll dilute it before I use it next time. Hopefully my plant will flower again. Thanks!

Don't look for an immediate turnaround. Several years ago I determined that I was overfeeding my plants, so cut way back, as I have suggested for you, and it took about 6-8 months before I started to notice any change.
