Struggling with deficiencies (nutrient lockout?)
Hello everyone, I need your help. I've been growing 2 Green Gelato Auto from RQS but I've had some deficiencies for a while now. It's my second grow and it's the first time that I adjust the pH. They are in soil and I'm feeding them with Biobizz liquid nutes at a pH between 6-7.

Yellow tips?
First timer here. What might be causing the small, yellow tips? The leaves sometimes look slightly pale but damn if they don’t look super healthy overall! I’m using minimal nutes thus far. Any insight? Thank you, thank you.

Deficiency?
I laid off the nutrients last week after some concern that I was overfeeding, but I think that resulted in a deficiency. (Some of the darker colors might be related to the strain? 🤔) The third picture was taken 12 hours prior to the first two, so it progressed quickly overnight

Leaves with yellow spots
We have find some leaves with yellow spots in them. The tips on new leaves are also turning yellow. Is this nutrient burn? Searching online I found it may be due to pH fluctuations, although we use pH controller with ferts (before ferts only bottled water pH ~5.5).
