calcium deficiency
Sorry, this had a typo. I have 90 watts of light, not 30 watts.
Also, all the plants are showing rapid growth. I thought that sag
leaves are just pale when they are small, but the "new" leaves are now
larger than the "old" leaves and they are still white.
Adeana
30 gallon
30 watts fluorescent light <<<<<<<<< really 90 watts
pH ~7
CO2 injection
sand over laterite/sand substrate
GH 60 ppm
alkalinity 80 ppm
nitrate 4.4 (LaMotte)
iron 0.05 (LaMotte)
The sags(dwarf) are showing new growth that is very pale, nearly white.
The older leaves are still green. The new leaves are beginning to turn
translucent at the base. The new leaves on H. polysperma appear slightly
crinkled. None of the other plants, crypts, sword, ludwigia evidence any
problems. Can this be attributed entirely to Ca, or am I Fe deficient
as well?
