RQS northern lights auto needs your help

Update:
I watered these plants daily, just like you guys advised. It worked for 3 of them, but northern light strain (most affected) is continuing to show some spots on the leaves. At first everything was fine and new growth was healthy but after the leaves got larger, symptoms came back. Since its in a bigger container than rest (18 liter other three in 12) i was giving it more water about 1.2 liters daily. But then i thought, since its smaller plant compared to others, it might be nute burn. And 4 days ago i started to give her different fert dosages (30% lower 0.9-1.1 ec). Newer growth has very small spots so i guess it did not work. Other plants are 3-4 times larger.

Are you still feeding it all those different nutrients? Fulvic, CalMag, seaweed, rootbooster? I'd stick to base nutrients at an slightly lower EC and work up as they improve in health.

Are you still foliar spraying them?

No i dont foliar spray anymore, i used all those nutes once 2 days ago. 3/4 plants are doing fine. Only this northern light strain is struggling. Since it sprouted it has 3-3-3 leaves growing insted of 2-2-2. I thiugh it was good but this mutation might be an issue idk. What ec do you recommend? I feed 1.5 ec larger plants and last watering i gave 1.1 ec to affected plant.

Based on the size of the plant about 0.8 EC. The 1.1 EC may be ok if it was just 1.1 EC of base nutes. I wouldn't be using all those additives.

I wouldn't worry about numbering of leaves.

IMO your lights are way too close.

Light distance is 18 inches. But other plants are taller and not affected? I think its a cal def caused by ph lockout. Planning to give 6.3 ph and check runoff for ec and ph.
