I have one question that is intriguing me.
I inserted 1ml of CalMag and 2ml of Biogrow in 1L of water as mentioned on the label of each recipient. The EC was 2mS/cm2. I fed the plants, in soil, with that mix and the EC of the runoff was 3,8mS/cm2. Looks like a massive increase of EC.
Can you help me with that?
Thank you guys.
@bs_monteiro It means you're over feeding mate. You should flush to bring the EC of the medium down a bit and feed less next time 
@macky I just flushed and the EC decreased to 1,2. Do you think it's enough or it should be lower?
