Note the bold face, I goofed when I said 0.65 as I meant 0.065 watts

as far as being able to tell if plants are showing deffiancys they will tell you what they are lacking or getting too much of by their appearance. Keep in mind it is normal for plants to drop leafs as they are constantly growing new, but a large leafs drop off means something is up usually. Are you seeing anything with your plants that is raising concern?
The bulb is 6500k, 20W

The java ferns leaves mostly all have brown spots. I think all the Mexican Oak died already. The anacharis looks good, the java moss looks nice but is slow growing after being in there for a few months. The hornwort is good. I just added an Amazon sword and thats looking sadder each day but I know some say that the leaves will die then grow back after moved to different tank sometimes.

Something about the Wisteria is making me think lighting is an issue. The leaves at the top look great, nice and green, and the leaves are close to each other on stem. But as you go down the plant there are fewer leaves that look sad and there are barely any leaves at the bottom. I have read that when there is far spacing between the leaves on the stem that there is poor amount of light, or is this just natural for Wisteria?

as far as your wisteria goes its probably a light issue. I have had mine for a month and had to separate it twice already thing grows out of control. but when its starting to get heavyuptop it starts to do what you are explaining happens with yours. try topping it and replanting the top to help get some light towards the bottom.

as long as you are seeing new leafs pop up on the sword all is well, but if its not putting out new leafs theres a issue which we can later discuss if this actually is the case. as far as the brown spots on the fern leafs maybe a picture could be better? java ferns reproduce by "spores" and they all come from the leafs this may be what your seeing.

Okay, this is kind of picture heavy.


Here's the top of the Wisteria


One picture of the java fern


Same bunch of java fern at different angle


The other bunch of fern


The Amazon sword (when I got it on Sunday only one of the leaves looked bad)


The big picture thus far

Potassium:Deficiency: Older leaves are initially chlorotic but soon develop dark necrotic lesions (dead tissue). First apparent on the tips and margins of the leaves. Stem and branches may become weak and easily broken.
Toxicity: Usually not absorbed excessively by plants. Excess potassium can aggravate the uptake of magnesium, manganese, zinc and iron.

here is a good link to book mark, this is one reason why you may be seeing but that doesn't mean dose with potassium right away. just keep using your flourish comp at recommended dose and don't get hasty. all plants are going to shed leafs all through their lifespan its natural. personally I wouldn't get concerned until 50-75% of the plant starts showing signs

and that bulb is perfect
