Potassium deficiency, Change your nuts to Bloom or u can make banana peel tea, banana peels in pieces place them in water, and then in a fridge for 5 days

When the pH around the roots jumps up and down, it can stress the plant and cause brown spots to appear on the leaves.This seems to often happen when the pH swings too high or low.

My plants are 3 years old (counting from soaking the seeds) and they are growing really fast but the leaves are a little bit yellowish in the middle. Is this some kind of deficiency or maybe something else? I’m a newbie to this and need your help guys ;)

CalMag or something else?Discolored leaves at the bottom of a 3 week young auto flower, full feeding schedule in diary. Was thinking Cal-mag deficiency, but after 4 days of running 2mL/L Cal-mag supplements it's still getting worse. Could it be lack of phosphor, and will BioBizz FishMix/Grow be enough?

New leaves have yellow and/or curled tips (-> nutrient burn?), and many leaves have their edges curled up (-> root problem?). The pot that I'm using is fairly small and only has a small hole for drainage. Can this develop into a serious problem?

Yellowing Hi! It looks like my grandaddy purple is starting to yellow, in my last week of veg (7). Could it be caused by too small of a pot (3gallons), this is my 4th grow, first time growing only one plant using scrog. Maybe an upgraded pot before I flower? Thanks!
