I was learning a lot just about water itself.
Currently the method I use was inspired by an article I found on Canna Nutrient’s website:
Rainwater + tap water to EC 0.2 (100ppm)
Add CalMag to reach EC 0.4 (200ppm)
Ph down (first diluted a small amount in water)
Nutes
Day 58:
Increased the feed to 3/4
Day 59:
Replaced the tap water to liquid silicon.
Rainwater + Liquid silicon to EC 0.2 (100ppm)
Add CalMag to reach EC 0.4 (200ppm)
Ph down (first diluted a small amount in water) to ph 5.6
