After reading your description, I think your Nitrogen deficiency more
accurately describes my situation..

I'll double check all of those readings again.... But if I recall, each of
them are low.. Maybe I need to UP my dosing of TMG???

I read somewhere that a 10,000 bulb doesn't really do anything for plants...
If that's accurate, then I really only have a 48 watt bulb at 6,700k... So
that's only 1.4 watts per gallon.. Think that may be part of the problem??


Thanks Elaine.

Hello,

I'm still having some trouble with the new growth on most of my plants...
Leaves are coming in yellowish, and some are very pale...

Here are some specifics:

33 Gallon tank
96 Watt PC lighting (48 watts @ 10,000k and 48 watts @ 6,700k)
Pressurized CO2 injection
I dose 10 ml of Tropica Master Grow 4 times per week
I dose 10 ml of SeaChem Iron 4 times per week (same days as tropica
master grow)
I change 60% of the water religiously every week.

I'm going to try doubling my dosage of Iron... but other than that, what
gives!?

Are you seeing yellowing, or chlorosis? Yellowed new growth AND veins in
older growth is chlorosis and indicates iron (or Mg or Mn) deficiency.
Yellowing of the whole leaves, plants quickly dropping old leaves, and new
growth coming in pale or stunted sounds more like nitrogen shortage to me.
Could be potash or phosphate as well, although I think TMG has reasonable
amounts of potash.

Have you tested your water for nitrate, phosphate, and iron levels? I
wouldn't bump up iron until I ran the tests because too much is bad for
your fish.
