Manganese used in EI?

The sites where I sourced micros back in the day are now carrying Mn in addition to CSM+B and Fe. Has this become part of EI? What does an Mn deficiency look like?

Any other traces I should be aware of? I'm planning to use CSM+B again, along with DTPE Fe for my 7.6 pH, 8 dGH, 6.7 dKH tapwater.

For me- yes. I always have issues with Manganese, potassium and magnesium. I dose with manganese because I find that it binds/in junction with the other two (and iron).
The baby leaves near the top of the plant show symptoms of yellowing.... just like magnesium (but magnesium hits the older leaves), IMO

Scientist found about 100 years ago that Manganese is an essential for plant growth. CSM+B has always had it. I don't know what a Mn deficiency looks like. Generally plants need a Mn level that is about 1/2 the iron dose.
