IMHO... you made the right choice for soil, RO > FF anyday. FF is inconsistent with their soil and I've had my problems with it myself.

The soil will feed your ladies for some time, that was two months ago...

What did you end up feeding them after all?

Next best thing to look for in your garden if you haven't yet is some compost tea. All the organic nutes are great but till you have a microbe population to get the nutes available and flowing to your girls your not unlocking the true potential of organics.

Hope your still around, let us know how things are going.
