What? Flush?
Another solution that works. Instead of a "flush" (leeching), would be to simply water it with a straight pH'ed water with like 3 ml of a Ca Carb based Ca/Mg, for like 3 days in this situation.
I might be inclined to simply add some N for a bit and drop that in a week or 2 back to normal use. Many ways this can go from here....
BTW Satori, I liked Nova too. The issue with it is, it's a cpl a points too high in P to start it's use right at the flip. A 2 week lay back and use of the veg for that time. Will avoid his problem...
Some schmeckle said top dress with oyster shell......NOT going to help at all! Don't.
