Orange Kush Cake R1 - Organic Grow

Hey friend, I don’t think that you have nutrient burn.I don’t know which plant you are referring to.I think you have nutrients lock out(some yellowish colour leaves)and nitrogen toxicity(some clawing leaves)due to improper soil pH and excess of Nitrogen in soil.Also 30C temp causes the plant to take up more nutrients that is widely available in your present pH and causing the Nitrogen toxicity.You check your soil and it should be around 6.0~6.5( run off).Happy Growing.. ✌️

Good morning, I'd say the leaf symptoms are definitely looking like a magnesium deficiency , fortunately you caught it before it started getting a lot of brown spots and progressing further up the plant. After doing your few foliar applications you might want to add some dolomite lime to the soil so it can have a steady supply over time. Just be mindful that lime products will raise the soil ph slightly. Otherwise you can always use the Epsom salt for watering the soil periodically as well. I can't say if it was the potassium lockout, or possibly the ph is off. If you continue to see more leaf troubles you might want to consider checking the runoff ph to verify it's in the right range. Good luck with the rest of the grow.✌️
