Do you even know anything about plant nutrition or do you just tell people to do stuff that will destroy their crop because you know what youre doing? Sorry if i sound like an ass but i hate the spreading misinformation and the thought of a new growers harvest getting ruined from bad advice irritates me.
First off, the dudes in soil AND hes feeding it...... i DOES NOT need more calcium or magnesium (
calmag is not a nutrient, calcium is and magnesium is also, and both can be deficient at the same time). Here are a couple charts to help you better understand nutrient deficiencies and excesses and i suggest you study them before you give any more helpful advice in the future. If you have questions about anything, just ask.
In the words of canadian icon Red Green: "we're all in this together"
Calcium def causes rust colored spots on the leaves and since it is immobile, it will appear at the bottom leaves first.
Magnesium def will present itself with perimeter chlorosis. The veins will appear neon green and while the rest of the leaf may still be dark green, there is a telltale, almost neon yellow that starts at the leaf tip and continues along the edges. The leaves will look like they have a neon yellow ring around the outer edge.
None of these symptoms are present and even if they were, since the grower is in soil and feeding them as well, it still wouldnt be an actual deficiency, it would most likely be a nute lockout from incorrect pH.
However, in this case there is an obvious N and P deficiency but whether its from under ferting or from poor watering practices (my guess is the watering practices), depends on what happens after they let them dry out a bit.
(theres an error in this chart. Calcium is IMMOBILE.
