I've got a couple Crypt. wendtii (red or brown....) that are getting soft spots on the leaves. These are not new guys, they've been around at least a month and some for 4 months. My C. willisii x lucens 'bronze' are not exhibiting this at all.

My water is fairly hard, higher pH (above 7) and the only thing that's changed recently is I started dosing liquid fertilizers the EI way. EXCEPTION: I "forgot" to get Phophorus (because I was having problems with too much phosphates), so I probably am deficient in Phos.

I have lots of Ramshorn snails, but haven't noticed them harming the plants as of yet. My pesky Rainbow fish nip at the plants, but they usually only nip the tips, not the sides/middle.

So, does this look like disease, definciency, or pest?





Thanks,

-Dave

I forgot to mention, I have root tabs in the substrate (put in new ones every month for the past 4 months). So, my original thinking was that I could get by without the liquid phos in the water column and dose the other liquids to combat algae. That's how I came to "forget" the liquid phos.
