its not letting me reply to what you said but the issue im having is that the plant wont grow the leaves just keep turning brown

3rd image from the top seems to reveal at least 180* of dead phloem tissue if not the entire cambium. Phloem is the tissue found on the outside of the vascular cambium. The phloem conducts photosynthate (the plant's true food, sugar/glucose made during photosynthesis) and other growth regulators/ chemical messengers from the top of the plant to the roots.

The plant's xylem tissues are located inside of the vascular cambium and conduct water and nutrients from the roots to the top of the plant. As long as the xylem is still able to provide the top of the plant with water/nutrients, new leaves can continue to grow for a period and the plant can survive on stored energy reserves. Energy reserves operate much like a battery. The energy held in reserve is finite, When the lights are exhausted, it's 'lights out' for the plant.

The cause of the issue is almost certainly to be an inappropriate grow medium or a hand too heavy on the watering can. If you haven't been watering over the sink and allowing the pot to stop draining before you return it to the cache pot, that too is an issue. The maim pot should never come in contact with the effluent that exits the drain hole.

The plant appears to be beyond salvation at this point, but there is nothing stopping you from flushing the grow medium, getting your watering under control, and hoping for a reversal. Ask if you want more specific advice ..... in case you decide to try another ponytail.

severely used up old media ... most likely leading to improper watering .... and in fact.. its so used up;. it only fill half the pot ...

when you water.. does the weight of the media change at all ... does any of the water soak into it .. or does it all just run off the the top and down the sides ???

the roots at the bottom look desiccated .. dried out.. but that might just be the picture ...

you have a two tier water problem ....
