Help with roots rotted
My Echinnodorus leaves started browning/yellowing from the leaf base last week. When I was cleaning up the leaves fell of as I brushed up against them. I lifted the plant and the roots were mostly just black stubs.
Any ideas why anyone?
Substrate is fine sand. I put in a Kugeln clay ball a week after planting, which was seven weeks ago. was dosing weekly with liquid fertiliser but I stopped about 4 weeks ago.
Thanks for any input.
