I'd start back at a reduced concentration for the first feeding.

My couple cents on flushing/growing organically is:
-Water to the point of runoff
-Use a humic acid supplement at regular intervals- I use it every week or 2- to prevent salt buildup
-Just stop adding nutes at the end
-During the last 2 weeks, continue to add your molasses and humic acid, and water to the point of runoff, and you will be just fine.

The nice thing about organic growing is that you aren't going to get as much buildup to begin with.

The humic acid supplement I like is called Soil Syrup, and it is CHEAP CHEAP CHEAP. Or anything with Leonardite in it will work. I mix it much lower than the rec. dosage since I use it more frequently. It is also an effective pH buffer.
