Substrate (Root Tabs Solid Ferts)
Could someone tell me how to tell when its time to insert root tabs or some other type of solid soil ferts into the substrate. My ADA Amazonia II is about a year old and has been fully rescaped about twice while being heavily planted.
I've been supplying my water with ferts regularly and its the first time several of my stem plants aren't looking to good. I've been adding ferts regularly... majority of my other plants look great. I'm noticing that my True Rotala Indica has been looking bare at the bottom and a lot of the leaves are turning brown and decaying from the bottom up. I was thinking it may be a substrate problem.
If someone would be advise me on this... much appreciated!
