No, I was specific with Rotala, if the NO3 is allowed to to drop, Rotala will not recover quickly. It'll grow like wildfire if fed.pineapple said:
Yes. Pearl grass is a weed, if you have trouble with that, something major is up. Go down the list, CO2, NO3, PO4/K, GH, traces.
Add more than you have been.
You should see responses quick with that plant.
You missed something and over looked it.
You can still do the PPS, just do a water change and re set things and keep going.
You can always revert back to EI to re set things and then start down the PPS path to whatever end suits you.
