Yes. I didn't want to spend $75 on a 25lb bag of Jack's so I got GrowMore Orchid 20-10-20 food with the exact same numbers. $9 at my local nursery and cheaper than Amazon that was going to take two weeks to ship!A 20-10-20 with 12% nitrate nitrogen and 8% ammoniacal nitrogen would suffice if I wanted to try to bring it down a little more?
Water to full run-off for a week and it will bring it down considerably.
