You use cal/mag every watering and feeding.

Cal/mag is basic nutrients that come in natural water.

Now the real question is what kind of water are you using?

you would only need cal/mag if you are using R/O water since the nutrients are filtered clean from R/O water.

If you are using something like tap water then your city has already added those basic nutrients in the drinking water.

So if that's the case don't use cal/mag unless you have a cal/mag deficiency

it is always best to use R/O water and add cal/mag yourself so you can have fresh clean water and control your ppms.

also the leave edges look curled? They are hot if so...
