I've had this plant for about 6 months. It has grown significantly.
I've been using Flourish once a week, Excel every other day and I started Trace twice a week about a month ago. The only plant that doesn't look great is the Windelov Java Fern. It started going downhill about 3 weeks ago.
It starts with brown spots on the older leaves, then progresses to yellowing, then becomes completely brown. There is still new growth. I'm wondering is it too much of something in the Trace, or is it a deficiency.
As a side note, the little arrow is pointed to a frog shed. he came back and ate it right after I took this photo.
This next one shows the younger leaves at the bottom of the plant which look ok.
Did you bury the rhizome? I can't tell from your pictures.
It may also be from the fern adjusting to your water. If new growth is coming in fine, don't worry about it. The old, injured leaves will grow out and be replaced in time, and they shouldn't hurt your water unless they turn totally brown. They will probably keep growing... you should keep them around because they may grow babies.
Could be a potassium deficiency. I suggest getting Flourish Potassium. I had a similar issue with my plants, along with stunted growth. It started with brown pinholes and yellowing on the older leaves, and eventually the leaves entirely melted. The top leaves were fine. The issue started with the quicker-growing stem plants and eventually started affecting all the others. As soon as I started dosing potassium, the problem started going away.
One thing a noticed with java ferns (all types) is when they are growing a little baby plant on the leaves, it sucks all the nutrients from that leaf. I also noticed that they will shed their leaves occasionally. But if neither of these are happening, dose some flourish potassium. Posted via Mobile Device
