I did just up my light PPMs so I think it is light burn but I want to make sure it’s not a deficiency like calcium. It only appears on the top of the plant, And nothing on the middle or bottom. Thank you so much
Pictures did not load
Not enough info, what type and what wattage is your light? What’s the distance to top of plants?
LIke @GulfCoastGurilla said need more info.
Please find and fill out a support ticket.Can someone point him to that page please?
Looks like Cal mag to me if it were light related I believe the top leaves would look bad as well from the pics they do not top leaves would be the hottest hope this helps that’s my thoughts
Totally agree with @JJ520 looks like ur n need of some Cal-Mag. Don’t believe it’s light burn because none of ur pistils look to b affected. That leads me to believe it’s a nute issue. More pics n a support ticket would help. A lot.
Sometimes called “yellow leaf spot” or “leaf septoria,” this condition is caused by a fungus (or sometimes a bacteria) that attacks cannabis plants and usually appears in warm, wet weather.
Thank you so much for that info. I’m going to research this
