Update
2 weeks ago i found out i had a co2 bottle empty for 3 days..
1 week ago my NO3 bottle emptied which i did not notice untill today....
Did a trim last wednesday.
Today i did a 60% WC.
Measurement
After i did the WC i couldn't resist to measure (since i saw from my plants that something is not good) and found these values:
KH: 3
NO3: 5ppm
PO4: 2ppm
NO3 is most likely due to the empty bottle, so i am ignoring that for now, but what about my PO4? Isn't that too high?
Other then that, something is missing.. I know you are going to say that it must be co2 related, but can it be something else, like to low micros?
Pics
I removed the Sunset Hygro and Giant Ambulia since it was weed as hell
Comments on the tank from a fellow hobbyist;
" You have to many same shaped plants on the left "
So i am now poundering to swap the Althernanthera for Ludwigia Glandulosa Repens 'Rubin' and see how that looks on the left side.
