I'm dont have experience with this per say but I have spent hours upon hours plus a couple days of reading never once have I came across "starving".
I've read of people waiting until the plant wilts to do their waterings or flushes but not actually starving the plants for 10 days.
Myself wouldn't ever try starving my plants to flush it doesn't make sense to me seems much more reasonable that fresh clean water will do the trick.
Test it out and you'll know yourself
