[APD] Corkscrewing leaves - name the deficiency

Name that deficiency:

My guess: Copper deficiency due to too much Zinc.

My Micronutrient contents:

Fe 20 g/l
Mn 10 g/l
Cu 0,52 g/l
Zn 2,9 g/l
B 4,0 g/l
Mo 0,75 g/l

Dosage: 2 ml in 300 litres when Fe-content reaches below 0,05 ppm.

(2 ml of this Micro should give me about 0,13 ppm Fe?)
