@BodkaBarrot, sheesh thanks m8

@Growyourhi, I am using r.o water / tap water 1:1. It seems like you put a lot of fine-tuning into your feeding schedule. Hm, I usually apply Cal-Mag depending on the conductivity, so I’m not sure how that compares to the PPM scale. Which Cal-Mag solution do you use? Also, I saw in your diary that you use the AC Infinity controller. How do you like it ?

@Growyourhi, did you use osmotic water when working with biobizz by any chance ?

@Growyourhi,I only use light mix without anything else (except the lime). But it’s funny that you also had problems with the pH when using Biobizz. I have been fighting with this issue for more than a year now. In my previous grows, I had to apply massive pH corrections since my pH was dropping below six (the lowest I measured was 5.7) – With the low pH came huge Cal Mag defficency symptoms. Now, I am slowly getting a hold of it. The problem was also that no one seemed to have the same issues as me. So, I am going to measure the pH in the soil once a week and generally water with a higher pH (7–7.5). Also, it seems that it depends on the amount of Cal-Mag used when watering. When I used pH-corrected water and 1.5 ml / L Cal-Mag, the system would run pretty smoothly. I use dolomitic lime now because I hope to buffer the system so the pH does not run away so fast. I also thaught about switchung nutes to canna but on the other side i wanted to find out how to fix the issue.

The amount of dolomite lime can probably be more than doubled next time: https://www.growweedeasy.com/cannabis-plant-problems/calcium-deficiency

@Growyourhi, Thanks! I wonder how much of a difference they make since I don’t really have a comparison. But overall, I like the handling and the fact that they don’t sit in water if something flows out.
