What does a CSM + B overdose look like?
I've been trying to keep my iron around 0.5 to 0.75ppm by dosing CSM + B. However, my plants seem to be having all sorts of issues. I'm seeing signs of major, contradicting deficiencies depending on the plant, especially the day after I dose 1/32 tsp of cam + b into my 22 gallon (more like 18):
Potassium - Pinholes, yellowing and melting of leaves besides the newest generation of stem.
Nitrate - Older/lower leaves completely dying off
? - New leaves on stem plants specifically seem to be smaller. These plants never recover even when moved to a low tech tank. It's like something was damaged internally, permanently.
I'm following EI and aiming for 20/20/5 nitrate/potassium/phosphate. Calcium is high due to rock, around 70-100ppm depending on how long its bee since a water change. Magnesium is around 10ppm.
