Cal-Mag question

Sillypup5started grow question 4 years ago

My general hydroponics nutrients have pretty clean & clear instructions, but the cal-mag, I’m unsure how much to use? Still just leaving the seedling stage this week, when I’m using 0.6ml/L of the GH nutrients, how much cal-mag should I use at this stage, and full on veg?

Hey I also use the same nutes, for the first week GHE says no cal mag and I put in 1ml for 4L of water. Also in the later stages around week 7 to 9 I bump it from 5ml to 6ml. Happy growing

best methods to start with fertilization advice on how to start fertilizing? I read on some blogs that it’s better to water first with demineralized water and then give some with fertilizers, and on other blogs I also read the opposite (first the water with fertilizers and then the demineralized one). opinions? 🤔

low pH problems I discovered that I had irrigated with water at pH 3.5 for at least 5 days. yesterday I used water at pH 5.7 and today I think it will increase to 6, but I noticed that burns are already starting to appear so should I continue like this and hope for the best or do a root wash?
