I would think that putting the leachate on/in soil [several days before planting] that is well aerated would take care of any problems assuming that there are any problems.

Many people recommend using the diluted (100 to 1) leachate as a liquid fertilizer around growing plants. I'm just wondering if there is any reason to believe there might be problems using it that way.

If this leachate is the liquid that drains off the bokashi 'brew', I would say it would be ok to use in a diluted form around growing plants. I guess you would have to try it to know for sure.

Just a note-

I've read that bokashi leachate has a pH of 2.5 to 3.5.

If someone is telling you that the leachate from a vermicomposting bin would be anaerobic and contain alcohol, etc. then I would know they have no idea what they are talking about since even the worms that digest the materials in a vermicomposting operation need air to function.
What I have read about Bokashi composting is that excess moisture, leachate, is about as desireable there as in regular composting, an indication of problems, a too wet mixture.
