Your measuring in ppm. EC is easier to work with.
What is your background EC (ec of the water straight from tap)
Any pics of the plants in full view. You need be feeding everyday to plenty off run off.

Use calmag as a foliar spray in veg keeping it out the feed 2-4ml to 1litre spray bottle. Every 10 days dependin of water hardness.

What else are they getting apart from AB?

Good tip that, ive always mixed my cal/mag at 1ml/ltr. Did wonder why i didnt find it as effective as some do.
