9 days of flushing in hydro (clay pebbles), is it enough ? Thx

Maskedcucumberstarted grow question 3y ago

6 or 7 days of flushing at 0.3 EC and leaves are still not yellowing. I fed them almost all run at 1.15 including 0.4 nutes from tap water which seems quite weak to me but they wouldn't eat more. I've been told from 4 to 15 days for a good flush in hydro. What's your experience ?

About 10 days before harvest I bring the feed down to .8 and see how she reacts. Typically I bring the EC down to .5-.6 by harvest time. (DWC) There have been 2 studies that show flushing is ineffective in reducing the nutrient concentration in buds. Not sure of the obsession of killing your plants before harvest. A dying plant is more susceptible to bud rot, WPM and pests. So keep them healthy and happy all the way through. https://atrium.lib.uoguelph.ca/xmlui/handle/10214/12125 https://www.rxgreentechnologies.com/rxgt_trials/flushing-trial/

High Maskedcucumber, Give it a few more days. It is an indication that when her leaves start to change colours that she is using her nutrition storage. I always flush around 10 days on coco. And I flush the coco pretty heavy with around 25% pot volume every time I flush. Happy Harvest! 😋

I do 1 to 2 weeks in hydro. Coco I tend to do 2 weeks. They don't seem to start fading till after a week of nothing but ph water. A week regardless getting nutes out of plant. After that it is just desired ripeness. Enjoy🤜🤛🌱
