Default Crook Crypts

Hello all!

Could some tell me if I am on the right track here??
My crypts (several varieties) over the past week (after 3 weeks of green
water) have developed translucent spots and patches, with some of the leaves
also curling lengthways. Now some of the leaves are disintegrating off their
stems. Does this sound like a K defficiency? I added some extra Sera Florena
yesterday, but so far, no change.
My tank:
DIY yeast CO2
2X30Watt flouros (dayglo and Powerglo)
150L
gH 6.7
kH ~3
pH ~6.8
I also have some flourish tabs in the substrate beneath them.

Any ideas??
Thanks,
- Seweryn

Default Crook Crypts

my crypts often look bent, and curling, I think that's a characteristic of a
crypt, but the translucent spots, are what is referred to as, melting spots,
where it is just dead in that spot... I generally cut off that limb and ONLY
that limb, because too much trimming on a crypt will make the whole plant
melt away... It'll come back with time, but it's not good for the plant to
be stunted like that...

Mine reacted to substantial water changes and good light more than they did
with ferts...

You don't say what your substrate is or whether you have other plants
that are doing OK. With the limited information, I think that metal
toxicity is a more likely diagnosis than K deficiency.

If you have other plants, they'd probably show a K deficiency before a
slow-growing crypt. On the other hand, there are many components of
fertilizers and substrates that cause problems in too high of doses,
including Fe and Ca. These toxicity problems usually show up in
slower-growing plants first.

The fact that this is showing up after green water supports this idea,
as the algae may have been consuming a lot of the problem nutrient.

I don't know what's in Sera Florena, or what other fertilizers you
use, but you may want to cut way back and see if things improve.
