Fine, it's one or the other. Let's get technical. Can you tell which is which, and why Calcium/Magnesium are put together in the same bottle? I think no, but it's possible you could have some superpower that I don't know about. All I can tell you is that the community here told me this is what was wrong. I'm a hydro grower, so changes in water chemistry to the plant is instant. Why did the symptoms of this plant disappear when I added the supplement, and why have I not seen this again since I started using it? If you know something that I don't, then let me know.
They put both in the bottle because both Ca and Mg are nutrients that are required in large amounts for most plants.
calcium helps with cell elongation, helps uptake other nutrients, strengthens cell walls, helps protect against diseases and bacteria and some others.
Magnesium is a building block of chlorophyll. Essential for photosynthesis, helps with the uptake of P K and Ca.
One of the reasons you get a Calmag supplement in the same bottle is because it’s hard to overdose on either one and both are required in plentiful amounts to sustain healthy growth and nutrient uptake.
Too much Ca can cause symptoms of an Mg def.
too much Mg can cause symptoms of a Ca def.
A calcium deficiency begins with small discoloured blotches on the leaves turning darker brown and red over time which then follow to over al leaf discolouring and necrotic areas followed by leaf drop.
a magensium deficiency starts as paling of the edges of the leaves followed by interveinal yellowing causing a distinct pattern to the leaves. Followed by necrosis and leaf curl up and crispiness.
not sure what else you’re actually asking.
wasn’t being a dick when I answered you to be fair was only stating it was not a CALMAG deficiency as there is no Calmag deficiency. It’s one or the other.
Doesn’t mean that the solutions aren’t the same though lol.
