It sounds good thanks.From a plant health point of view, from what I can see, everything is growing well and you've got no algae.
Absent any evidence of nutrient deficiency, I'd be tempted to leave as is.
if it ain't broke don't fix it.yeah I agree. I kept plants for years not realizing anyone ever did anything but just stick them in the water. The easy ones can grow and thrive with just what the fish produce. There are tons of fertilizers and methods of fertilization, etc. but it is a deep rabbit hole and heck, your plants look pretty good to me. Much like Mikeyboy123 said, if it ain't broke don't fix it.
yes, it's quite a bedtime readheck yeah! I stuck with a 29 gallon for years, then quit the hobby. Came back with a 15 gallon and now i'm working on a 75 gallon (here's the journal if you need some sleepy-time reading). I've promised my wife that's the last one, but every flat surface in the house has potential- I know I want at least a nano shrimp tank and a nano reef tank.... far in my future (the 75 gallon will take time).
More tanks more tanks more tanks!!!
