Glosso Turning White?

[NyteBlade]

I'm having a bit of a problem in my tank. A few leaves on my glosso have literally turned white. They aren't really translucent, they appear to be white, or atleast very very pale. I can't tell if it's new growth, old growth. I suspect some type of deficiency but the glosso was grown emersed too so it could be adapting I guess.

I have 130 watts of PC over a 29 gallon. Pressurized CO2 - bubble checker shows a consistent green. I've been following EI to a tee except I've been a bit lax on traces and iron. Water is fairly hard - 8 GH/KH I believe last time I measured. I suspect it could be an iron deficiency but I'm not entirely sure. I'm going to up trace dosing a bit via CSM+B, and maybe start adding additional Iron in the form of Seachem Iron and see what happens. Any other suggestions or causes to this?

When this happens to my Glosso it usually means that it is time to change bulbs.

But it could be an iron deficiency too. I routinely over dose on the Flourish iron - a bit. And I also have Flourite as a substrate. So in your case try dosing iron. Another thing my Glosso really likes is phosphate. It responds rather quickly when I up the phosphates.

The fixture is nearly brand new. I'm pretty sure the light that came with it was new (it was a refurbished unit) but either way, I know one bulb is new . They're dual daylight 6700k/10000k Sunpaq bulbs. With over 4 wpg, hopefully light isn't my issue - maybe too much light.

It could also be phosphate. I've throttled down phosphate dosing too to keep levels hovering at 1 ppm, but I think phosphates may be one of those things that you can't do any damage with if you have too much (within reason).

I'll try upping the iron dosage as well as the phosphate, maybe a little bit of everything. There's no fish in the tank though so I might need to add some more fertilizer to compensate. There will be angels soon though. Mwahaha.

And make sure you have enough CO2.....!!!!!!!!

The drop checker is a solid green so I think I have enough CO2 in the water. I'll pay closer attention to CO2 levels. My best guess is iron at this point though, so we'll see how it goes. If there's anything else I'm missing, comments would be appreciated!

Just a quick note about CO2. This my opinion only. I don't believe drop checkers are 100% accurate about the amount of CO2 in your tank. They are good INDICATORS but in no way are they 100% accurate. If your Glosso pearls then you have enough CO2.

Using my awesomely bad photography skills, I managed to get a picture. It seems like only some of the growth is affected (presumably new growth). The Ludwigia Repens might be exhibiting the same type of thing but it's hard to tell. You can see some of the leaves seem quite a bit paler then others.
