Leafs Folding Over
I have two Wisteria plants that are now submersed. They were subjected to emersed conditions and have the spear like leaves when I purchase them through mail order. They appeared fine as I planted them but within a few days, the older leaves have turned over.
I suspect not enough liquid fertilizer is being added ( once weekly ).
I wonder if its the same reason my Ozelot Swords have developed black marks or marbling?
My lighting is two aqua-ray grobeams 1000 over a 75 gallon long tank and are 9 inches above the water line and 13 inches above the tops of the wisteria and swords. Could it be a combination of both of not strong enough light and need of more fertilizer? The plants have been in the tank for 3 weeks now.
I also have 3 Anubias that were planted the same time and appear ok.
The Anubias are actually tied via thread to a piece of driftwood.
This plant does need nutrients, being a fast grower, but it also needs lots of light.
Listed below is the only data for my AquaRay grobeams 1000 nd as available from "Tropical Marine Centre". Their company is located in England I believe.

This evening as I went over my water parameter data sheet which also has my dosing instructions; I noticed a big mistake.
I was not dosing the liquid fertilizer correctly as per instructions. (Sometimes the metric system gets me confused).
I was only dosing 1/3 of the amount weekly or 10 ml, when it should have been 30ml once a week.
Thanks for responding and I'll try not to make big mistakes again.
I'm very unfamiliar with LED lighting, but those numbers look good. I'd leave the lighting as is. And increase the fertilization per instructions. If problems occur or persist, post and I'll take a look.
As a comparison (since I've looked into the LED lighting thing) an 18" T8 6500K fluorescent bulb is 700 lumens.
So with two of those LED fixtures giving you 1600 lumens I'm thinking could be low light for a 75 gallon. Unfortunately, lumens don't exactly mean a whole lot in aquarium lighting. You would need a PAR meter, which are extremely expensive. So really, all we can do is guess.
I have Wisteria though, and when bought it too was the emersed form. The curling of the leaves is exactly what mine did. At three weeks though, have you seen new growth on the top? And roots coming out of nodes? You should see at least some, even in low lighting (like I had).
The submerged form of Wisteria is pretty much completely different, they almost look absolutely nothing alike.
Yes, there are roots growing out of the nodes. When you said curling, I think you meant your plant leaves folded over and not up; correct? I believe theres a differance when leaves fold up or down as to what may be wrong.
In my case, I am suspecting shock along with insufficient fertilizer.
They've gone both ways with mine, I don't really remember though.
Here is a picture of my Wisteria that shows the new growth. To be honest, I think it looks way better than the emersed form, it is actually my favorite stem plant that I've tried so far.
The wisteria you have is a standout. When I placed my order for same, the company did not say I would be getting an emersed type wisteria. I will not be placing an order with them anymore
I did see one of these in my lfs and it was just like you have.
Well, like I said, mine was the emersed form too so given time, yours will switch over like mine have. I had bought mine at Petsmart.
The reason they grow it that way is it grows much faster out of water since it is far easier for the plants to take up CO2 from the air than water, not to mention brighter lighting and not having to worry about algae. In short, it's easier and faster.
If they didn't say it was emersed and showed pictures of the submerged form though, I'd probably have issues as they were kind of misrepresenting it.
