13views and no replys. i could realy do with a little bit of advice

I use cal mag my self in the res. Good Luck

cheers for that 3days later plants look 100% healthy will keep that in mind next time.

go get yourself a bottle of botanicare's Cal-mag, use at 50% at al times if you have clean or R/O water, its good because its a 2-0-0 so that added nitrogen is a big help in early flowering

sound for that information mate i will keep it in mind.

Try to hit a nutrient ratio of at least 2:1:2 or up to 3:1:2 depending on whether in the veg or bud stage and depending on the amount of leaf to your strain. Run Calcium about equal to your Nitrogen and your magnesium about 1/3 the ppm of your calcium.

You are talking about NTF (nutrient thin film) I assume?

Canna products really are not very user friendly for indoor inert media hydro growers. Like many California manafactured mj specific nutrient products they tend to worry more about supplying water suoluble fertilizers for outdoor growers that inert hydro formulations for indoor growers. They are typically short on or totally missing many micro nutrients, calcium magnesium and sulfate.

Cal Mag is just Calcium Nitrate, Magnesium Nitrate. Cal Mag plus is Calcium Nitrate, Magnesium Nitrate, Iron EDTA. Typically if you have a mag shortage you are also likely to be deficient or nearly deficient on calcium and iron.
