This book I have says nitrogen deficiency shows as yellowing tips of leaves starting with lower/older leaves. I’m on my first grow too, so I’ll defer to others and am interested to hear what it is.

YellowingHi! 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!Leaves. Color - Yellow
