Current Grow (3L coco autos) : Jumper's 2020 shenanigans
15 gallon root pouch you say, do you have good drainage in the bottom and anything mixed for aeration ? Sure looks like a Phosphorous def to me that can be caused by wet compact soil.

What is your drainage like? If you are getting that high of an outflow, I would think that there is an overdose of something other than nitrogen at play. Nutes tend to make things acidic and with high EC levels, it sounds like a lot of nutrients are already in the soil. If you have water issues, it can cause issues with nutrient absorbtion, as can nutrients themselves. I'm guessing the soil is fortified by the manufacturer, which is the reason that you aren't providing any additional nutes other than Cal-Mag. I think you are seeing a nutrient lockout which is caused or compounded by overdoses of either P or K... plants change their requirements during vegging and flowering and I have noticed that folks often get a surge in outflow about 2-3 weeks after switching to flowering mode/12-12. I would flush it a few times and maybe give a foliar feeding of Cal-Mag, which can bypass the roots and get the nutrients where it needs to go. Foliar feeding is a great way to figure out lockout issues as it goes directly to the plant... just don't make the solution too strong!
Are you using coco/hydro nutes for soil?
Just using the FLOWER TAB by Nirvana. I add CalMag to every watering because of R/O. The last couple waterings I've added trace amounts of Liquid Kool Bloom (0-10-10), and Floralicious Plus (2 - 0.8 - .02). The total PPM is never more than 300 since flowering.
Im thinking about a major Flush tomorrow. Ill check the runoff every 10 gallons to see what it's at, and hope to get back up to 6.5 Ph.
Does that sound like a plan?

No need to check ppms and ph in soil grow.
20% coco is just for aeration- wont make the medium hydro from a feed point of view
Gardo - so dont flush tomorrow?
How do we get her back to normal?

Hopefully someone will else will add some info as ive not had this before but i would still say flush out the rootball and then feed. No ph adjustment ever, i am sure of that going forward.
Just use ml per litre for any liquid feeds too not ppm
Kbag, the soil drainage is awesome. In the root pouch it usually takes three to 4 days to dry out. When I water her she'll way near 50 lbs. When shes really dry, she only weighs near 20 lbs. I seriously dont think there is any compacted wet soil.
