Yeah way to much calcium... 300ppm??? With just cal mag added... eeesh. Tap is likely close to 80%cal and then adding that much more... not to good.
But I also think there is a lot more going on here.
Looks like too much calcium locked out calcium and now progressing...
These in rockwool?
What would you do to correct it? Not add extra calcium and lower the ph ?
flush some out and use as needed. I don’t know how to manage 50/50 coco/ peat. I was warned to keep coco content under 30%. Maybe calcium is the tricky part ?
I think so..triying to figure out...I am flushing with liwer ph and not EC
what you mean " coco under 30% " ?
When I did my first grow I always measured the tap water EC and then used CalMag to bring it up to 0.4, I was having something similar but on much smaller scale but you are 50% higher on the base even before nutes.
I was growing in Canna Coco Pro Plus mixed 70/30 with Perlite and using Canna nutes though so not exactly a like for like comparison
