Re: Calling on all Marsilea folk... Hey melauriga!
That's interesting that it started with multiple lobes in your El Natural. My daughter had me put some in her El Natural and all the new leaves are single-lobed and tiny. But, it's also fairly new, so maybe the soil has not yet released much in the way of nutrients?
I know what you mean about dosing ferts. I'm in the same boat as you and getting ready to start my own first NPT, Walstad-style.
