It's time for another game of....DIAGNOSE THIS DEFICIENCY or DEFICENCIES!
I need help on this one, I'm new to plants, and judging from what I've read...it almost looks like a sulfur deficiency and CO2 deficency, but I can't tell...

The anachris gets a bit thin in the middle, and also has tiny white calcium deposits on it's leaves towards the top part of the plant. I believe I've read this is a sign of a calcium defiency.

On parts of the hornwort near the tips/parts of the plant, it's actually "lighter" than the rest of the plants and less green.

Also (not pictured), there's a few stems of the Jungle Val that actually have little green horizontel lines going part a section of the stem...so it looks like...

(Not the same pattern sorta random, but the - represent the green slashes across the leaves that are deep green compared to the rest of the stem).

Thanks for the help, once again ;)

Possibly from lack of light, those particular plants don't actually need ferts or CO2 to live, but a lack of light could cause those symptoms; what size tank do you have and how much light?
 
Pictures are too blurry to tell much.

How big is your tank and how much light do you have?

The yellowing of new leaves can be due to lack calcium or iron. The green slashes in the vals may also be a sign of iron deficiency. A bottle of Flourish should do the trick.
 
29 gallon has a 65 watt CF Sattelite light fixture
I leave the light on for about 10 hours a day. The hornwort in question is towards the side of the aquarium, so it might not be getting as much light as everything in the middle...

The anacharis that has the white dots/gets a bit thin in the middle is directly in the middle of the tank. (Also, I meant to say that I read that this was a sign of CO2/Sulfur defiency, not Calcium defiency.)

EDIT: I have a bottle of unopened Flourish that I bought that I have not dosed as of yet, so that's easy enough to start doing. :cool: Hmm, the plants don't need CO2? Would firing up this Hagen CO2 system hurt anything?

1) The Flourish is always good for your tank.
2) All plants need CO2, just how much.
3) The Hagen would help, but you do need more light.

What spectrum is your bulbs??
 
Satelites come with 50/50 bulbs, no? Did you change them out to plant bulbs?
 
They look a heck of alot better than some of my plants :)

If you have only 65 watts on a 30 gallon tank... that's not alot of light. The wpg rule isn't that accurate with smaller tanks. You will end up needing a little more light than that to get good results. However, if you do go higher than you will need CO2 and ferts. They don't look bad to me (the non blurry pictures) so I wouldn't worry to much about it. Test for NO3 and PO4. Do you have hard or soft water. Have you checked your PH, KH, and GH lately?
 
no, the lights fine, 65 watts should grow anything fine on a 29 gallon tank, especially those low watt plants.
 
You are getting bad advice from the people saying you need more light. That is plenty. CO2 will definitely help, but when you add this you will increase the nutrient requirements of the tank. Right now it doesn't look like it's too heavily planted so you won't need to increase ferts too much.

Hornwort should do fine in half the light you have, it's not demanding. Anacharis in anything above 1.5-2 wpg should also do fine.
