Weird yellowing leaves.

Hey guys/girls,
My friend's girl is showing some weird yellowing. Can you give me an idea of what is going on?
Wattering with BioBizz nutrients: 2ml FishMix, 1ml BioBloom, 2ml ActiVera and BioHeaven, 2ml TopMax, some drops of Calmag.

Whats the PH of the water your giving. your amounts are they ml/L? Are you feeding every water or doing a water,water,feed? Do you have an EC/PPM pen to test water going in to runoff. What kind of medium are you growing in?

I'm guessing its under feeding, But hard to tell with the info you have provided and burple pictures are not very useful.
Could also be your light is to close. what led are you using and how far is it from the canopy?

Even under blurple I see potassium deficiency. Take pictures in normal light for better advice.

Better pictures please. Looks like interveinal chlorosis but normal lighting pictures would help massively
