I have some cryptocoryne and some lately show an excessive downward curling of the leaves. Not all crypts have this but till now only the Indonesii and Willisii show this. In a way this developing waving leave edges is natural for most crypts.. But with these types it lately became more looking like curling inworths than waving.
Now did some searching and couldn't realy find much about it, but 1 that could make sense. It was said if an excess or up change in Nitrate causes the leaves to curl in and takes time for the plant to addapt to the new parameters.. This made sense to me, i started noticing this growth patern since i changed to use dry salts as ferts and also added 10ppm KNO3 in the regime. Before that with the tropica complete the plants didn't show this.
I know i have Nitrate in the tap water and nitrate ofcourse is produced by the lifestock. So for now i stopped adding KNO3 and for now only add KH2PO4 and K2SO4 and see if it changes back again.
Anyway, my question is, anybody else experienced this symptom with crypts and can confirm it is indeed an excess or change in Nitrate?
