From my perspektiv, it should be good for Cattleyas too,
because Ammonium brings the water/substrate more to the sour side and the best PH is arround 6.5 ?!
Nitrate allone raises the PH, so from this Aspekt, it is a good choice.
I also noticed that seedlings grow better with ammonium in the fertilizer.
That's why I created my Fertilizer myself, with K-Lite Idea in mind, but not so extreme.
It works fine, but I haven't a longtime-experiance now
11,94 N - 3,72 P - 5,0 K - 4 Mg - 4 Ca - 4,3 S + TE
Arround 40% of the nitrogen is ammonium.
The PH of my RO water with this mix is arround 6,5 to 6,8 , 0,4g/l and a EC arround 400 us/cm
So, If I would live in the US, I would give the new K-Lite formulation a try
