Burmeseanswered grow question 5 years ago 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.. ✌️
