I just stsrted my first flushing ppm reads 475 ppms.Should i flush again when soil dry in 3 days to get it lower thand flush again in 3 more days to get under 50ppm?
No harm in that plan. More typical would be to flush more now until you reach your runoff ppm target. and then water only until harvest. You won’t drown them at this point. For your next grow, you should create a single grow journal topic (versus a new topic each week). So friends like @Myfriendis410 can track your grow.

That’s about 400 PPMs lower than the norm Growmie. Maintain 800-1000 unless you’re nearing harvest and would recommend water feeding only versus a flush

To flush out nutrients?

What growth stage are the plants in Growmie and the nutrients you’re using? Only time a flush is needed is to reset the PH. Sometimes a flush is needed when the grower was not feeding to run off and the salts from the synthetic fertilizer accumulated in the root zone driving up the PPMs much higher than the plant can tolerate, these accumulated salts will also tank the PH……reset PH flush mentioned above

If you’re doing a before harvest flush hoping for a better end product, you will get mixed advice on that. As some prefer the flush and others feel it does nothing for the plant. I’ve flushed and not flushed in soil and coco grows and i can never tell the difference. Give it a try and see if you can. Its never hurt my plants to flush them at the end of their lives, but i cant say its ever helped them either🤷‍♂️

A water feed only the last 2 weeks would do the same as a flush without the work needed to flush the medium
