I've got these deficiencies? In some plants. I'm having trouble getting a solid answer of what I need to dose. I have osmocote root tabs, dose flourish excel every 2 days, flourish comprehensive once every 2 weeks. Substrate is flourite and a current satellite plus light. Tank is a 40gallon tall. This is actually my father in laws tank and he's asking me cause I got him into live plants....and now his tanks look nicer than mine...
The flourite itself doesn't have a whole lot of nutrients. Some iron and clay but the osmocote tablets that are in the substrate have a lot of nutrients.
Since you have tons of fish Nitrogen and Phosphorous is not a problem....I suspect they are lacking potassium. I am no expert but NPK is basic things that needed for avg growth since you are having holes in Leaves that means the plant tissue is breaking.
