Hello
@CapitanKush ! No it's not wind burn. Two things this might be. Heat stress or the beginning of zing deficiency. If you moved your lamp closer then move it a little further if not then it's zinc deficiency ( very common micro nutrient deficiency ). Excess phosphorus, low temperatures and ph fluctuations can affect zinc absorption. First check your ph and if it's wrong correct it. Second if your ph its ok wait a couple of days and see what happens. If the problem continues or you see it happening more aggressive add a micro nutrient mix with some zinc. Happy growing ! 👊
