Here's a brain scratcher - I'd be willing to bet that most of us on here use or have used Botanicare's Cal-mag or Cal-mag plus. I have yet to hear of anyone growing with any of their nute lines.
I used their Pure Blend grow and bloom for 8 years. I also used their calmag product until I realized it's not needed if you're already using a complete plant food.

I mainly use the cal-mag to supplement reverse osmosis (0ppm) water.

Often, early stage K deficiency is misdiagnosed as a Cal or Mag deficiency so people up the Cal-Mag. IMO
Maybe. But since I started using the cal-mag full strength (5ml/gal) instead of reducing it with my nute % I have yet to see the same "K" deficiency, so it is what it is.

If you don't mind me asking, what plant food bottle/bag/formula were you using where you noticed some sort of deficiency?

The calcium deficiency usually starts with the little brown spots surrounded by yellow, which grows until the leaf turns crispy. The Potassium deficiency looks similar, but is usually more yellow than brown at first, and it starts at the tips and works it's way up the leaf.

Regardless which deficiency it is, not shorting the cal-mag has helped for me - this could just be the cal-mag keeping the balance right so that potassium (and other stuff) is absorbed better.

The way I look at it, the cal-mag is just returning my RO water to "safe" tap water. The RO removes both the good and the bad stuff, but then you put the good stuff back in.

Fox Farms original trio then Fox Farms Gringo Rasta. I am now growing successfully with both, and that is the only adjustment I have made nutrient-wise. The thing is, it's really hard to tell the difference between a deficiency and an overabundance - so were you shorting something or giving too much? I am leaning towards a lot of my issues being deficiencies rather than overages, and my recent results seem to favor that as well..

Like I said, this has worked for me so far. Your results may vary.

Hey guys why do you think my one side is growing way slower than the other? I can’t figure it out the entire plant has been treated the same.
