The wisteria I got about a month ago has started turning yellow and losing some of it's leaves. Can anyone tell me what is wrong and how to get it to perk back up?

Water quality checks out (0 ammonia, 0 nitrite, small reading of nitrates) although I do have fairly hard water...GH was 10-11 when I last tested.

Weekly waterchange of about 20% and I've been using ThriveC (for low tech tanks) once a week per the instructions on the bottle. The substrate is flourite that came used six years ago. I added some seachem root tabs under all the new plants when I got them a month ago and most of the others seem to be holding their own or even growing new leaves.

Light is a finnex fugeray that I've had for six years or so, although there's quite a bit of duckweed. The wisteria is not quite centered under the light, but it's probably in one of the brightest places available.

I just retested and yeah, nitrates looked closer to 5 than to 10ppm. I am pretty surprised because the tank is about 6 years old and although I have been doing weekly 10-20% water changes for the last couple of months, I hadn't been very on top of regular water changes or gravel vacuuming for the previous year. The timer on the lights died while I was traveling this summer, causing a die off of the out of control guppy grass that then led to a bloom of BBA and prompting me to buy the new plants and get more serious about tank maintenance.

Also, kH was only 1 but gH was up around 10 or 11. pH was 6.6.

Any thoughts on what I should do?

Oh, and no I don't have a PO4 test kit.
