When I did Ebb & Flow hydro last year I had good success.
This year total crap out with coco coir.
The major difference was with hydro, I would adjust the ph to 5.5-6.0.
With coco coir I didn't bother adjusting the ph.
I took a reading of my tap water and it's at 7.5-7.7 with 134ppm.
That's way too high! ph should be between 5.5-6.5 anything below or above will lead to nutrient deficiency.
What's your tap water ph ?
