Please help / deficiency

Growlog link: [https://growithjane.com/growlog/unbekannte-sorte-7axn]
I don`t know why there are spots on the leaves I always use ph down for the water to get 6.5 ph.
And for 1 month I use BioBizz CalMag Nutrition because of the deficiency. I had in the past problems because of my bad ph use.
Is it possible that my grow can still get a healthy growth ? Or does the plant even regenerate ?
Please help.

What’s your light source? Right off the bat I think you need to transplant it as soon as you can because that pot could be stressing the plant out with the lack of oxygen and nitrogen it’s getting through the soil. If the soil gets too compacted in a small pot like that you’re going to run into a lot of problems. I think you could still save it but it looks like it’s done growing since it’s already budding. Let’s get some input from @Sedrik777 or @209MIKE

I agree with @520grower that pot is far too small, it’s going to be jammed full of roots all intertwined and no oxygen or nitrogen flowing through. I’d be surprised if there’s is any nutrient uptake to be honest. Not a bad thing, just will have to take some strategic planning to correct. Minimal size pot for small plants like that I would say would be 1-3 gallons. My general rule of thumb, the root zone is going to be roughly 3 times as dense as the canopy. So what you see up top, double to triple and that’s how much space your roots take up. It is still possible to save the plant, I would start with a transplant but given you’re already in flower that’s gonna be tough. You don’t want to shock the plant anymore than it already is. I would maybe try increasing your nutrients slightly to see how the plant responds

I 100% agree with @520grower and @SoulOurGarden on this one, I would transplant into a 3 gallon pot ASAP. Being rootbound in flower is almost guaranteed going to restrict oxygen to the roots and you’ll end up with small and airy flowers vs large and dense. With how large the plant is already the soil should all come out in one piece because I’m sure the roots have consumed every bit of room in the pot and you should see a drastic improvement within 7-10 days. You might experience a little wilt from the leaves after you transplant. But the pros of transplanting now vs letting it be are very much outweighs the cons of transplant shock. The roots will most likely be stuck to the pot so take your time getting it lose if you do decide to transplant it. Best of luck @lukas4fa
