What do you think, which deficiency could this be?
These pictures are from my 40L low-tech shrimp tank. Since it is now temporarily housing 35+ tiny 2,5 month old juvenile fish I have been doing more water changes than usual. I have been adding one pump of Tropica fertilisers (either Specialised or Premium) after each 50% WC (about 3 times a week).
I was thinking of iron, but the affected leaves aren't necessarily new. The anubias is showing yellowing with green veins. The crypt leaves that turn yellow are mostly lower ones. I could just add more Tropica ferts but it would be nice to be a little more specific if possible. I have an old bottle of EasyLife Ferro and all the EI salts too.
