Ovo ti možda pomogne... Mislim da ti fali P i K. Koristiš samo mikro + CO2, a samo mikro imaš u podlozi, ribe daju dovoljno N, al' očito ne i P i K.
Ili prestani koristiti Profito i EC da je potrošnja jednaka i biljke imaju manje potrebe koje je lakše zadovoljiti (i malo smanji rasvjetu) ili gnoji i s makro jer samo s mikro izgladnjuješ biljke. S makro možeš i preko podloge: ušpricaj zemlju pod korijen većim potrošačima il' gurni osmocote.
Ovakvih tablica ima još puno (i detaljnijih), al' ova odgovara na tvoje pitanje:
Nitrogen-----------entire plant turns yellow green, and the older leaves become
more yellowish than the younger. Older leaves do not die
unless deficiency is extreme (almost never seen in aquaria).
Phosphorus---------Plant stops growing and becomes darker green or stays green.
Some species may become purple with excess anthocyanin
pigments building up. Other species do not produce excess
anthocyanins and just stay green and small.
Calcium------------ (1) mild deficiency---Smaller, distorted new leaf growth.
Reduced leaf tissue, with the central vein persisting.
Leaves often cupped, rather than flat. (2)moderate
deficiency---Often sudden bends or twisting of leaf, which
is now much reduced in size. White streaks or white edges
in new growth. Roots are stubby and twisted. Root
tips may
die. Leaves of Vallisneria are strongly crinkled as
though
they have tried to grow and got jammed in a small space.
(3) severe deficiency---New growth almost entirely white.
Leaves are tiny deformed stumps. Growing points for both
shoot and root die.
Magnesium-----------In dicots---Yellowing of older leaves that starts from the
egdes inwards. The midrib may remain green while the edges
are yellowed or whitish and dying (I don't know what this
deficiency looks like in monocots like Vallisneria, but it
should involve death of the older leaves. )
Potassium-----------Small dead areas appear in older leaves. These can start
like little pinpoints and grow. In some species, like
Ceratopteris, the older leaves stay green while the little
dead spots grow. The new leaves are reduced in size and
leaf area, looking a bit 'singed'. In other species the
older leaves can turn yellow before they die, but they do
not have green persisting along the major veins as in
magnesium deficiency.
Iron----------------Reduced chlorophyll in new growth. Leaves and stem are
about the same shade. Growing tips of Ceratophyllum become
pinkish and then white. Eigeria densa tips become greenish
yellow to yellow with the leaves small and clasped close to
the stem. The new leaves of swords are smaller with
patches
or broad streaks extending lengthwise that are more pale
than the rest of the leaf (in mild deficiency). In more
severe deficiency in most plants chlorophyll is lacking
completely in the new growth which soon dies.
Boron---------------Very similar to calcium deficiency. New growth is
distorted and smaller, and then the growing tips of both
roots and shoots die. In mild deficiency in Crypts, the
leaves are cupped and the roots are shorter and distorted.
