Confirmed Toxicity?

Although my tank is thriving, I believe my L. Glandulosa is suffering from some type of trace/micro toxicity. Both lighting and Co2 are calibrated correctly (40ppm+). I've been dosing EI for a while now, and I notice that some of my plants (particularly these) aren't responding well to Micro days. For now, I've discontinued dosing micros in an attempt to restore healthier growth.

Before anyone says "it's a calcium deficiency", I will say that's definitely not the case. Our water supply has large amounts of calcium, plus there is calcium in the substrate via root tabs. Here's a coupe of pics. Advice/thoughts would be appreciated.

I think it's just a super difficult plant to get right. I do agree it's more sensitive to micros it seems. I've had 6 stems for about a year and they would go from nice not twisted growth to twisted in a week. I just swapped my substrate to K aquasoil in an attempt to try to get it together grow better. I suspected my 3 year old eco complete had too many root tabs under it causing the issue. Hoping to see good new growth in a couple of weeks of adjusting.

Probable micro-tox, especially if dosing EI levels of traces. Pictures of the other plants would help.

If that is wisteria behind it, the light may not be bright enough to make the ludwigia color up. Those wisteria leaves look like they are in a lower light environment.

How long have you been dosing those levels of micro?

few months.
i reduced from original EI because my AR mini got twisted bad at the time.
to be honest i dont blindly believe micros was to blame(i upped co2 and stopped using glut also back then), but since i havent noticed anything bad since i reduced them, i stay with reduced dose.

If the reduced dose is still working, no need to increase, so you're definitely right.

Do you have pictures? Just curious how yours looks now. I had the same issue with my AR mini and stopped dosing micros for like 3 weeks and they grew in amazing. I dose about 1/5th micros now, but my glandulosa still is twisted like OP's photo.

possible Boron deficiency, too much NO3 can lead to deformation of leaves if water is soft.

Are you sure that is glandulosa? Doesn't look like any I've ever seen. Different leafs big time. Unless mine just looks so deformed from issues, but the leaves are much more narrow.

im quite confident it is. i keep photos of name badges after plant purchases.
might be the low light effect maybe. i will soon boost the light back to 100%. im still waiting for all plants to adapt after replanting before i do so (altho this particular plant adapted in no time and started to grow)
