Two of my plants clearly showed magnesium deficiency. I was able to improve it a bit with 1.6-1.8ml/L Calmag, you can still slightly see it on the newest leaves at the tips, but it's not as bad anymore, also on biobizz light mix. You should know your calcium and magnesium levels in the watering water though.
