Cal-Mag Plus...How often to use? Photos of deficiency symptom, I think.

[Roguejim]

Some of my plants are showing signs of calcium deficiency, i.e., new growth crinkled...

At the rate of 5ml per gallon, how often should I use it? The plants seem to be requiring water about every other day or so, but I know this will change as they grow larger and the roots run deeper.

I would feed with it once a week and foliar feed with it once a week too at dusk.

How often depends on how much you are using. You can safely use 1/4 strength weekly, or full-strength every 2-3 weeks. Post pics of your plants - "crinkly" leaves can be a number of things.
