I accidentally fertilized my sago potted plant with orchid fertilizer. My fonds started turning yellow, so I added Epsom salt, confusing magnese with magnesium. I now have the proper fertilizer, diluted correctly, I hope. My question is this: Do I fertilize with the liguid, (a slow release 3-4 month type) as I would water it, I.e. thoroughly? And would I then thoroughly water it? Or should I just fertilize? Also, should I do that from the top of soil or from the drip tray to be absorbed from the bottom? Thank you so much for any help you can give me regarding my baby.

Unfortunately, it could have already caused too much damage. The first thing that you will want to do is to find lab grade citric acid. (It isn't expensive, and you can find it anywhere online) Mix a few tablespoons into a gallon of water, and water the whole thing through the plants soil area. Then water with pure water (tap is fine) and after that you may fertilize with the correct fertilizer.
Make sure that you take the drip tray off so that there will be no standing water. They will quickly rot if you leave any extra water. You may top feed and water as usual.
Indoor Sago Palms grow very slowly and use very little nutrients. I suggest that you skip the fertilizer altogether. If you are getting yellowed fronds it is probably due to inadequate light or improper watering.
