You can run this in soil. Just don't bother trying to run any beneficial bacteria. Mycos do seem to do fine with salt based nutes but other stuff not so much. I would up pot to some ocean forest and let them shake off the stress before you throw them under a brighter light personally.I'm thinking flora nova is for a hydro setup, not soil. I could be wrong about that. I always use the fox farm trio (soil) with the soluble trio and things work out well. I also use the fox farm ocean forest dirt, I guess you could say I'm a fox farm fan.
Oh, is this already flowering? What size is the container? Is it healthy? Pics?I wouldn't switch my soil and risk complication at this stage of the grow.
Wait for next batch.
Everything might go good and the the girls adjust easily but why risk it?
