I'm day 33 into my grow using canna terra pro as the medium + nute range. Everything had been going relatively well until last week - the tips started tinging yellow which i assume was nutrient burn.
Since then i've been feeding plain water pH to 5.9 as recommended. Last couple days i've noticed these spots on a few of the leaves and can't pinpoint what it is?
I was just about to top this and turn to flower but want to make sure i've found the issue before doing this.
From my research it looks like it could be phosphorus deficiency? Or maybe calcium?
Any more experienced heads know what i might be looking at? Any help appreciated!!
