Is this a good cocktail for my next feeding? I’m having major nutrient deficiencies or something. These yellow leaves got me stressed.

Yellow tint on new growth
I've spotted some yellowing on new growth. I'm just in the end of Week 3 and am thinking it's caused by nutrient deficiencies? I've been sticking to 0.25ml/L and am planning to go to 1ml/L starting Week 4. Does anyone have any other ideas?

Deficiency or Nute Lock?
I was a told a week prior I was feeling too much. So I stopped. I left town for 4 days and came home to the current photos. One looks like nitrogen deficiency, the other looks like calcium deficiency except I've fed 1tsp of tiger bloom, .5tsp of Cal-Mag and big bloom last week.

Leafs yellowing
What can this be? It happened in 1 day. Is plant asking for nuts? I added only water for 4 days because i was afraid of been giving to much nutrients. Could be a pH problem?

Meine Pflanze zeigt aktuell leichten Kalium Mangel. Aber irgendwie nur auf eine Hälfte der Pflanze. Die andere Hälfte sieht gut gefüttert aus. Kann mir das jemand erklären? Also warum betrifft der Mangel nicht die komplette Pflanze?

Is this nutrient burn? Had what looked like a lack of nitrogen early on, lowest leaves were healthy then quickly went yellow and worked up. Now have fed nutes at 0.7EC (tap water left for 24hrs to 0.28EC) so fed under 0.5. Bio-grow 0.5ml/l bio-heaven 1ml calmag 0.25. Thanks

Leaves full of brown spots
My friend doesn’t have a grow diary but he uses advanced nutrients and feeds when almost dry. He has this problem on his leaves and he can’t seem to stop it. I suggested calmag but he feed it 2ml per litre on sunday and the problem is still increasing. What else can he do ?

Possible toxicity or deficiency?
I saw this on one of my bottom leaves this morning. Hopefully someone can give insight of what it might be. I'm concerned that it is phosphorous deficiency. I didn't notice it a day ago, but I wasn't looking closely. 2 days ago I watered her (540 mL, 1/4 tsp nutrients). Thoughts?

45 days flowering yellowing
45 days of flowering, is it a bad yellowing or it's normal for this phase? Always did 1ml/L of biogrow, I think I'll put 2ml/L till flush. It's nitrogen, right?
