Limnophila aromatica
These pictures of two stems of Liminophila aromatica were taken 18 days after dosing high levels of boron. The newest leaves are twisted and deformed, and the growing tips have died off. It appears very similar to the symptoms of boron toxicity of Rotala “Vietnam”.
Here is a picture of the first stem (back left) taken just 5 days before, 13 days after the boron experiment. The leaves show normal growth patterns. (The white leaves of the stem on the right shows iron deficiency chlorosis from being grown in inert sand while the stem on the left is grown in nutrient-rich clay.)
Why did it take so long for excess boron to adversely affect L. aromatica? Perhaps it’s due to the thickness of the stems which can hold high concentrations of nutrients for use later, or perhaps it was due to chronically high levels of boron which the plant could no longer tolerate. Regardless, a 75% water change was performed after this observation to help reduce any excess boron in the water column. Let’s see if this results in healthy growth.

Hi, I added two Osmocote plus balls near the roots of my Limnophila Aromatica two weeks . I also dose E.I levels of micronutrients. Do you reckon I could have some sort of toxicity? I give you the link from the thread I started on tpt. I would appreciate your input.

I apologize for the late reply. Life has gotten in the way of maintaining this blog.
Just looking at the picture, it’s likely a nutrient related disorder. But what exactly can’t be identified.
Just how much Fe relative to the other metals are you dosing? Excess Fe can induce deficiencies of all the other metals (i.e. Mn, Zn, Cu.) What is the GH? Is this tap water? Do you have copper pipes?
