Thoughts on this leaf issue?

Light: HLG 320w 3-board QB-288 rspec @ 18-20"
Ventilation: 440cfm exhaust on the QB heatsink
Temp: 78° - 82°F
Rh: 60 - 65%
Soil: Ocean Forest 5-gallon smart pots
Nutrients: Green Planet Medi-One base, with Liquid W8, massive and finisher.
Additions: Mycos and Asoz added to soil at transplant before flower.

Feeding schedule:
Watered every other day.
Beginning of each week they get nutrients, followed by water the rest the week.

2.6qts per watering, PH of 6.4 both when plain water and with nutes.
They received cal-mag once a week in plain water until week 3 of flower.

Nute table: Screen Shot 2020-03-17 at 5.22.57 PM.png - only once per week, currently in week 4.

Plain water the rest the week.

The one thing I don't have is a PPM/EC meter.
