Hello, looks like PH Problems. If the newer leafs okay and the symptoms stopped no problem. If there will come more leafes in the middle and lower section like this on the picture i would check PH.

Thankfully not my plant but what do you think this deficiency is? My first thought was actually that one plant fungus r something that causes brown circle like spots. This is the top of the plant. No curling to leaves.

Dark purple areas on leaves — genes or environment/feeding problem?What the heck is this? Is it just purple genes or a stress/deficiency or a combination of multiple factors? I have checked three visual cannabis plant health guides, and did not find a single issue which looks like this. Maybe a combination of 2 factors, but I'm not convinced 😐

So in the last 3 pics from Day 22...am I seeing a calcium deficiency? She gets tap water, which I was hoping has sufficient calcium. But now I'm thinking I might need some Cal/Mag. Is she hungry for calcium?

Mehrere Mängel 2. Grow with Gorilla Cookie Autoflower seeds. The deficiencies on the back left look like those on the back right, I think phosphorus based on the pictures, and in the front, it's pretty much a mix of everything but extreme. The only bud that smells when you touch it is the one from the back right, the others don't.
