if 1050 ppm is elemental ppm calculated from gauranteed analysis labels, it's probably a bit high. It's weird your EC is listed as 2.2, because if it convered that to ppm it'd be 1100 on equipment using the '500-scale' conversion factor.
got some wind there?
Your vpd is even lower than the stated atmospheric temperature. Even without subtracting 3-4F it's in a good enough range. 77F / 65% is 1.11 kPa, so that's not burdening the plant.
I wouldn't worry too much about this if your climate is correct and consistent. I bet it as it matures it doesn't even show these signs in new growth. Depending on how that ppm was derived, may need to adjust that but time will tell. If you run into overly lush plants in next few weeks you know to start with a lower concentration next time.
The balance of crop salts is awesome out of the box - just like masterblend, southern ag, jr peter's jacks 321, megacrop et al.. they all use a very similar ratio of nutrients and it'll work very well as instructed, but definitely take notes of your dosage over time... The symptoms you will run into will be slow-moving and a culmination of weeks or months of time.
