I’ve been doing k-lite at 25PPM for a bit over a year now with most every watering. No signs of fertilizer burn ever. The only time I don’t fertilize is when I apply Kelpak/quantum total once a month. Some of the standard Catt’s put out absolutely huge growths this year. Many are in sheath now, with a couple beginning to fill the sheaths. Had one of my C. harrisoniana put out three growths this year, which is about triple what it normally does. I think you’ll be happy with this fertilization rate.
