Yellowing on tips and leaf edges

Hi people,

Harvesting is just around the corner, but can anyone aid in diagnosing this late stage issue? Is it nute lockout, calcium or magnesium deficiency, normal nitrogen deficiency (usually not so edgy) or something not mentioned?

Much obliged…elliot

Hey @elliot ,
The vast majority of the time things that look like nutrient deficiencies are actually something else.
The support ticket that Midwestguy posted helps us to determine the entire situation and give accurate answers. You should not trust information based on a picture only. It would be like telling a doctor you have a pain in your stomach and him giving you meds without finding out the actual cause of the pain. A symptom in cannabis can have multiple causes. All of us have worked to figure out growing this plant indoors and want to help. Any answer you get without more information is just a guess It may or may not be right.
Look forward to helping out.
