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

I grow one plant in a five-gallon grow bag filled with coco coir. I water her everyday and on every third day I feed her with my nutrient solution. Everything so far has been good - growth, color. The pH and PPM of solution is 6.5/ @1500. What do you do when growing in coco?Week 5

Hydroponic PPM and feeding. How do I match magnesium sulphate to potassium for flowering??Do I got this right? Hydroponic Flowering cannabis eats at a rate of 1-1-2 and for maximum useage, feeding 1-1-2 makes sense. Extra nutes outside the ratio is wasted and extra. You want highest PPM possible before burning. Will extra Cal-Mag burn roots/leaves?Feeding. Other

Terpinator (During Flush or Not)For those of you who use Terpinator, do you prefer using it up until harvest or do you prefer still cutting out everything during your flush? I know its' advertised as being able to use during flush so I'm not worried it's unsafe. Just figured I'd see what my fellow growers like!Week 10
