Nutrient opinion

So my first grow I used plagron nutrients all went well then I upgraded to advanced nutrients and I’m having problems my plants are showing signs of calcium magnesium iron and potassium deficiency but I’m giving them the recommended dose plus Cal mag has anybody had experience like this should I go back to the first nutrients
Plants are 7-week old photo period and 3 week-old Autos all under 600 watt HPS light on 18/6 light schedule

Pictures in white light would help.

This all happened over night
