Nute burn? What now?

I would flush if you have been fertigating? you don't have any nutrients listed or you just feeding plain water in soil?

Hi budy! This looks like P deficiency to me..? Is that possible? You do not mention any nutrients in your diary, so I cannot see if you added too much. It's also possible that you added too much Calmag so that there's nothing happening anymore.. It would be the best if you would water with a bit runoff and measure the EC and pH of the runoff, so you can react the right way. I would guess the pH is too high.. then I would water with pH-ed water to correct that first. Happy growing!!

High bro, Nute burn is ofcourse cause by too maby nutrient salts inside the soil. You can flush these salts out of the soil by giving 2 times the pot volume in water. So if your pot is 10 liter then you give 20 liters with water for once. Make sure that you are using water with the right pH and without nutrients. When you did this you let the soil dry out. You want the top 1-2 inches to be completely dry before watering again. When watering again you can start to give nutrients again. But start with a little (50% from the amount that you gave before). And to prevent this in the future give water till 20% runoff ocasionally (once every 2 weeks). Enjoy your grow buddy!
