Browning on leaf sides and tips

Hi there Marley, that's magnesium deficiency as you can see from the discoloration on the edges of the leaf. If you can do anything about it then you can spray on or water with epsom salt, cal mag, or extra Mg. it's already quite late to use it but if you do use it you'll see some improvements almost immediately. Fix this now and hopefully you'll have time to recover before the flush. If you're actually in 24hours of light , then you should reduce it as much as you can. The plant will use more Mg to regulate photosynthesis. Hope this helps ! 🚀

Hola! Parece una sobrefertilizacion. Tenes medido la EC y pH?.

You have nutrition burn the brown curled in tips is the indicator. In flowering you NPK ratio is 1-2-3. So in you case now I would do very little nitrogen from here on. Also make sure you are getting adequate run off. If providing bottle nutrition without proper run off of 10 to 20 percent to push out old nutrition you will have a build up and may be the the main cause. Good luck 🌱

Hi there. I know she is an auto but I would recommend adding at least 2 hours of darkness to your schedule. Check your Ec and Ph of your runoff and see how much its out compared to your input solution. If your medium is out of range in the ph scale you will be getting nutrient lock out.
