I checked the PH level of my osmosis water after I added Canna CalMag Agent and measured 5.8 - I think this is a bit to low for a soil grow. I start now to add 100ml tap water to every Liter osmosis water and have a PH level of 6.5 and EC of 0.5 before I add the Hesi nutrients.
Watered every plant with 1.5L

Cleaned the environment, defoliated the plants and prepared anything to take the autopot system into production. I will start the blooming stage soon.

Changed the light schedule to 12/12. Watered 6/9 plants with 1500ml - rest will follow tomorrow.
Turned on the airbase system - it will run during light cycle and when the temperature around the pump is below 25°C.
The Hesi nutrient scheme is reducing the ph lvl of my water below 6 and am asking myself if it is really good to have such low PH for plants potted in soil. Be ware that I use Osmosis water and mix it with a bit tap water and canna calmag to adjust the water before adding Hesi.
It's a little low for flower, if you were in veg I'd say don't sweat it as veg cycle does better a little acidic. Are you running an airstone in your reservoir? Depending on how long it sits it may be beneficial plus it will likely raise your pH a little bit too.
