Pics of Plants with deficiencies

Hoping you or someone else can diagnose what the Sword needs. We've already established that the Wisteria needs Potassium.

Here's the Sword. Notice the prominent dead area at the end of a leaf.



Here's the pinholes from the one Wisteria - The part that was cut and planted is doing fine so far. Pic is kind of blurry.

Had some trouple with the pics. You'll have to look a little down aned a little to the right for the pinholes.

Thanks,

Steven

DarkCobra Hard to tell. It looks like potassium plus iron deficiency.

But I'm going more by your current tank description than the picture, comparing the conditions against times I've had similar setups. The pic is too small to see certain details, like pinholes. Some of the visible algae that may act as clues aren't reliable here, since they may be lingering from what sounds like a recent lighting downgrade. And judging nutrient levels by plant appearance is a bit more art than science anyway, especially when multiple deficiencies might be involved.

Django One more thing - is the Sword suffering from the same deficiency as the Wisteria?

Thanks,

DarkCobra I don't know where you heard that you can get sufficient macros from tapwater, but it ain't true. Unless your tapwater is so polluted you really shouldn't be drinking it, which looking at your water report, isn't the case.

You're probably getting enough nitrate and phosphate from fish food, rather than the tapwater. But not enough potassium - which you've already correctly diagnosed. And a good micro fert including iron would help too.

Off the shelf at your LFS, Seachem Flourish and Potassium at doses recommended on the bottle will fix you up quick.

Looks Like Fert Deficiencies - What to do?

I have a 10 gallon tank and I don't do macros - supposed to come from the tap water (very soft) - See attached pdf file MWRA122012.pdf for tap water report, page 7.

The Sword has parts of a couple of leaves dead and translucently tan. The Wisteria that I took off the other Wisteria has pinholes like Potassium deficiency.

Today:
pH: 7.6
NO3: 20 ppm
GH: 6
KH: 5

I had 2 10w CFLs over the tank, thought they were too strong and took them out and substituted one (1) 13w CFL. The Sword has been growing like crazy, putting out a new leaf every 2 or 3 days. Nothing has died yet but for the most part (except for the Sword) they're just not growing.

The fish are fine - 7x Pristella Tetras. I just did a 30% water change. I usually change 2.5 gallons of water once a week (25%).

Any hints? Thanks in advance!

Steven

Oh, a pic of the tank from the other night. Attached.
