So my wisteria has been doing good for the past few weeks that I have had it, new leaves sprouting from the substrate, and existing leaves starting new growth. But some leaves haven't done anything, and some are even getting brown spots on them.
What would cause this? And does wisteria repair its leaves? or should I trim these off?
I would suspect a nutrient deficiency. Several authors mention that iron is especially important for Wisteria (Hygrophila difformis) and suggest an enriched substrate (tablets/sticks will work) and/or a liquid fertilizer. I wouldn't recommend iron alone, as plants require macro-nutrients and micro-nutrients in balance, and adding just one frequently results in an excess which can cause some plants to react, resulting in deficiencies with respect to other nutrients. Wisteria is a relatively fast-growing stem plant, but does quite well under moderate light. Some recommend 2-3 watts per gallon of full spectrum light, but I grew this plant for a few years with a 15w tube over a 20g tank although the lower leaves regularly withered away and I simply cut off the stems and replanted the tops.
Thanks Byron, I just started using API's Leaf Zone last week in this tank. We'll see how that works out. If not so good, I might think about doing some hard fertilizer (non-liquid.)
And thats about what I'm running now, 16g tank with a 15w bulb. It's getting growth, just like I said, some leaves aren't happy.
I've not used API's Leaf Zone myself, so can't comment on its effectiveness. I did check their website, and it seems to indicate that only chelated iron and potassium are included in Leaf Zone. I'm not saying this won't work, but as I mentioned previously plants require a balance of several nutrients, and all these are missing from Leaf Zone. Some may be present in tap water, depending upon its source, and of course some come from the biological processes in the aquarium. But from my reading I suspect not enough of the necessary nutrients in porportion.
I've had incredible plant growth in fairly low-tech aquaria (see my 70g and 90g aquarim photos) with Seachem's Flourish Comprehensive; according to Seachem, it contains a balance of what's needed, and this balance is consistent with the advice of plant experts that I've researched. Here's a link to their info if you're interested:
I've also had success with the Kent Freshwater Plant Supplement, some years ago (1990's) but same results in the tanks.
Also, it can take a couple of weeks for differences to become noticeable, so having got Leaf Zone I'd give it a chance before switching. Of course, the downside is the plant may wither to nothing... Let us know the results.

Thanks for the advice. I'll take a look into that Seachem, so in case Leaf Zone doesn't work out I'll switch over. I saw a bottle yesterday as I was picking up a light strip for my 2.5g, just didnt look at it.
And I LOVE your tanks. I've looked at them before and was amazed. :-D
And yeah, I figured I would give it 5 or 6 weeks to see what kinda results I get from it. Now that you mention it, I'll go ahead and take some pics tonight, seeing Leaf Zone has been in there half week, which means most growth was just from the stand alone tank. Then every week after I'll do the same thing, from the same camera position. That way we can see what kid of a difference it makes on a weekly basis. :-)
So since I'll keep updating this, I'll change the title some and list my parameters:
I'll just be adding the recommenced dosage, well a little over, as I am dosing for 20 gallons when I have a 16 gallon.
One more note, I have a low-light set up, 15 watts on the 16 gallon, and no co2 YET. Based on some rough calcs, my current co2 is about 5 ppm. Since Anacharis grows fast no matter what, I'll exclude it from the pics, I was thinking of focusing on the wisteria and Java fern, since wisteria has shown decent growth, and the fern is an ideal plant for low-light.
That little an overdose won't hurt. I slightly overdose my tanks twice a week.
I've never bothered to measure CO2 since I have no intention of adding it, so I figure what's there is there and it either is or isn't enough...obviously it is enough for the light and other nutrients. Again, balance is the key. I believe you will do well with your light and liquid fertilizer.
Thanks for your kind words on my aquaria.
I would personally suggest Seachem Flourish as well. I just started keeping live plants for the first time as well. I also am growing some Wisteria. I have a 10 gallon with a 15watt Life-glo full spectrum bulb over the tank. Regular gravel, No co2, and dose twice a week with Flourish. I, so far, have seen signs of growth in all of my plants. My wisteria are baby plants but are growing little by little. I personally am convnced that Flourish is a good all around fert for plants.
Yeah, I have heard good things about it, from several people. I was going to try it, but when I went it, my LFS had just ran out and wouldn't be getting any for about 2 weeks =/ so I just decided to try this. Figured it couldnt hurt anything, and I have heard a little about it as well.
If it works for you, by all means keep using it. I was just putting my review out there, in case you do decide to use something else.
I see you took KH readings but no GH or Phosphate. If your KH is that high your GH is going to probably be double meaning you have hard water. Your nitrates are pretty low for a planted tank. I looked at a bottle of the stuff you are using a few weeks ago when I was at PetSmart and saw that is doesn't have what is needed.
I also don't like to dose mixtures of ferts. a little reading and you will probably want to go a dry route where you can dose individual elements.
