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.

Deficiency issue/problem with leaves Any idea what problem I’m having with my plant/leaves? I’m guessing some type of deficiency because I’ve only fed once and it was a few weeks ago. (Check photos in most recent week). Any advice/ tips would be awesome, thanks!
