I see you have a fairly high ammonium salt to nitrate ratio for the N. My hydroponic system with beneficial bacteria encouraged to grow, sees a dramatic drop in pH if I use any NH3 salts in my nutrient. Lowering pH with acid is way easier than raising the pH in the system. Nitrates do cause an...
Where I live, the early Ukrainian settlers brought hemp seeds with them. The used it for clothing, cooking oil, animal feed, etc., until they made it illegal. Same thing when I was in Northern China in the early eighties. Huge fields of pot being grown by the peasants
I can see why people like growing in soil. The early development is way faster than hydroponics. The runt in the dirt farm got culled since it wasn't growing. One of the Do-Si-Dos is a bit yellow. I may have a touch too much N. I will add some water to the reservoir to dilute the mix a bit.
