Hi guys! I’ve had this plant for a few months now, I think it is possibly a Jade, but I am new to succulents so I’m not sure It looks discoloured and spotty, could someone help tell me what’s wrong with it?

I couldn’t get the picture to upload here... so linked it on imgur.. https://imgur.com/a/C2gwGcN I recently transplanted a small ornamental Phalaris grass my friend had divided. For a couple weeks, it did well, with new green shoots growing. In the month since then, it's done poorly (minimal growth, yellowing/browning blades) The 3 gallon fabric container medium is Coir:Perlite @ 2:1 ratio. I water with MaxiGro complete/stand alone nutrients at moderate strength, pH'd to 6.0 Suspecting fertilizer burn, I stopped nutrients and flushed with only water for 2 weeks, and the plant deteriorated even further. Re-introducing nutrients gave a short, initial improvement. What's wrong with my grass, and what should I do differently?

Ok, so overwatering was not the problem, because when I let the soil dry an extra day compared to before, the leaves have begun to dry up (wrinkled, shriveled, headed for crispy). I’m now wondering if the MaxiGro nutrients are not working well with grass. (I’ve used it successfully with other potted perennials). So to change that up, I sprinkled 1 TBsp of slow release Miracle Grow into the top layer and watered deeply. If if this doesn’t improve things, then my next guess will be the potting medium. But again, other plants have done well in the Perlite amended coir. I was trying to avoid peat.

I also questioned size of pot in my original post, but didn't say that you should use smaller one. Karen is right. If you find that plan is tipping pt over, you can place a larger rock or 2 on top of the mix. I use large rocks to support newly repotted plants, but they can be good counterweights too. Or use pot that is not so deep but wider at the base, so it is more stable. Terracotta/clay pots are also more stable, because they are heavy. I use mostly plastic for that reason. I also mentioned that I would cut of leaves that are mushy - didn't say that you should since I really can't see the mushines in your photo. I keep succulents in smaller pots. Not because "they like it" as some ppl suggest, but for lack of space. If plant gets too big, I rather divide it and give away some. The reason I do not grow Aloe vera - it's leaves grow quite long... I know that pp used put some rocks or pieces of broken terracotta pots over drainage hole to prevent mix from falling out. Use piece of window screen or any other mesh with small openings. Or even piece of landscape fabric (it lets water thru), or coffee filter. Even piece of newspaper will work, but it will decompose.
