Hey guys transitioned from soil to coco perlite grow. Having really high run off readings 1000-1800ppm on 700 scale in 3rd week flower. Just flushed with clearrex still came out similar readings. In 3gal fabric pots I didn’t think to flush while in veg or use a flushing agent until just now. I’ll add light feed in a day.

What do you guys recommend to get ppms down?

Thank you for your help.

What ppm are you putting in... just wondering. Plant pic looks great.

100-150 cal mag and clearrex that’s what it came out. Was feeding 700-900 but obviously was building up. I’ll update next feed. It just blew me away how high don’t want to mess up the plants.

Put in base nutrient Flora nova bloom, botanicare raw, silica, cal mag. Ppm around 490-510 run off was 800-1000ppm on most and some 1400-1800.
