Hi All,
I'm 5 weeks into my first grow and I'm a bit worried as my leaves are starting to go brown at the tips. After reading some previous posts on this forum, I thought I had a nitrogen deficiency, so I topped it up. Now I'm not sure if I overdid the nitrogen top up, didn't add enough, or if I've another deficiency. Does anyone know from looking at the attached picture?
