NOT positive but its possible you have some root rot going on? That happened to one of my potted mango tree and the leaves looks very similar to yours...very droopy. Ironically, by the looks of the tree you would think its suffering from lack of water but in actuality its from soil that is staying way too wet towards the bottom of the pot (perched water) and the roots on mine were rotting. Your potting mix looks VERY water retentive to me...they prefer mix that fast draining, keeping the soil moist not "wet". Is there a way you can very gently remove the plant being very careful with the roots and check to see if the bottom of the pot is very wet? You can also insert a thin (wood dowel) sharpened at one end...insert it all the way down towards the bottom of the pot and see how wet it is. This is just a guess since its hard to diagnose from a picture...Best of luck! Nancy

Peach and citrus respond very well to compost teas and micro-nutrients. I would strongly suggest using a compost tea that provides both. You can easily research how to do this on your own or find a commercial tea. If you buy a tea you need to brew it I would not suggest any pre-made teas and really look at the ingredients. Believe me there are some really good teas out there but most are honestly just worm castings with one or two feed sources, which you could easily buy yourself. This is a photo of my sick peach tree. I planted this in very late spring and had bought it bare root. While it may not look like it I have been battling a serious fungus all summer. The key to this trees success has been keeping it healthy. I did this with compost tea and worm castings.
