I noticed some yellow spots on a leaf the other day after asking everyone decided on calcium deficiency so I added some calmag to bring the dose up to 2ml per gallon for 16 gallons of ro water and my ppm is only at 133. All I am using is bergmans nutrients, hydroguard, calmag and ph up/down here are two pics one from yesterday and one from today does it seem worse or is there something else I should look at?
That is likely progression of the deficiency once the plant experienced it. They may turn black and develop holes too. I think you are just fine. Although at this point it may be time to start with the nutrients.

This is my second week of using the bergmans seedling nutrients. I was told to start out using about 1/2 dosage. Monday I do my weekly water change and will start the veg nutrients more than half strength
I would go 5ml gal on calmag.
Awsome that really helps a lot!
