New Mega Crop nothing like old?

I had similar problems with first grow using pro-mix. Our tap water is soft 3-8 ppm.
Started using cal-mag, re-using soil, and amending with DR Earth tomato vegetable and herb + Flower girl

I am using MC at about 4-5g.
When you amended with calmag and other nutes did you just add them to the same water as MC?

With the cal mag yes because it is liquid. The DR earth is a dry organic. I mix it in before planting and top dress some after. I don't keep good records for amounts, sorry. Another thing I like about the dry organic fertilizer outdoors, may/june is often wet so plants don't get watered much, it separates watering from fertilizing.

I have almost stopped using cal mag recently.
