          Do you ph your water? Which method do you use to check and adjust ph?

          How big are the pots the plants are in?

          temperature? Highs and lows? Is 19.3 a consistent temp? Or does it get colder?

          This is a necessary start to determine what is wrong with your plants. To guess based on a quick look can lead to more problems.

          Everybody who is going to grow the weed needs a bottle of cal-mag give her a tsp every other feed. Even when there are no issues.

            Been growing for about 10 years now and never once used cal-mag.
