Looks like natural leave colours to me, don’t worry too much just keep an eye on it. Leaves are prone to develop mutations

Yellow edge with brown spots on fan leaves
I am wondering if anyone could help me figure out what is going on here. She’s been healthy all grow, but in the last week has started showing the weird yellowing/browning on a few leaves. The temps, nutes and light haven’t changed really. Anyone have any idea what this could be?

Was ist los ? Magnesium mangel oder Stickstoff..Hilfe
Hey Leute, Ich weiß nicht was los ist. Meine Damen sind irgendwie traurig. Vor 14 Tagen wurden sie umgetopft und haben jetzt 2 Mal Dünger erhalten. Davor 10 Tage lang ph eingestelltes Wasser. Dünger ist Canna Terra und gegeben wird 3 ml auf einen Liter Wasser plus CalMag.

Why are there soon many brown spots all of a sudden in WK 7?
I'm entering Wk 7 and the same lady is hurting again. She's been feeding heavy for last few weeks and doing great. So, I gave a light water/microbes dose w/can and Epson. Now I think its potassium or something else entirely... Brown spotting, yellow, crispy? Thoughts?

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?

Did I do the right thing? Pls check my update on this week!
Can my Growmies check my update on this week please? Ppm shot up and I noticed nute burn. Weird bc I have only added water since last week. I cleaned the pump, removed air stone and lowered ppm. Definitely seems like too much nutes - hoping they’ll perk up.

Rust-colored margins and dots. Potassium excess, Calcium excess, or something else?

Biological Cal/Mag alternative? It appears the cal/mag from BAC is mineral feeding, is that correct?
Starting to see what looks like a deficiency of Cal/Mag. I'm trying completely biological and I can see the Cal/Mag under the mineral nutrients tab from B.A.C. Is there a biological alternative?

Light, nute, wind or heat burn?
Im getting some browning on the serrated edges of the leaves, moreso on the upper fan leaves, but not on the sugar leaves, with some cupping of the upper leaves and the ones directly under the light are getting a lighter color overall. Any guesses? Light, nutes, wind or heat?

Nutrient lock out?
Well watered my plants with great value drinking water. Ph 4.11. Didn't check ph until week 3. Currently upping it to 6.5 after I found the issue. Does this look like nutrient lock out? They were in root Riot starter plugs. And I fed the some clonex and great white microbs.
