flushing with tap water

is it ok to flush with tap water i was thinking to flush my plants in my bath. I was gonna use a mix of cold and hot water. So the water wouldnt be as cold. Just luke warm not hot. Will this be ok its the last 2 weeks of flowering i want to flush out the nutes before harvest. Please let me know whats best to do.

Im sure everything will be ok. Just do a quick check on you Ph if your a little worried or just do what i do fill a few gallon jugs up and let em set for a few days.

Hank.

fill the bath and let it stand for a day, if you can.
or buy lots of bottled water.
i collect rain water in a dustbin outside, and when i flush, i just dip the pots into the bin.
tap water straight from the tap, is bad!!!.

i flushed them so now i wont feed them at all just water them if they need it, not long now till harvest

Nice, yeah, I use straight tap water that I ph down. I was filtering it before, but that was a huge hassle, and my plants are doing great minus my slight nute burn...hehe.
