That looks like to much light intensity to me. Theres a chance it could be the start of a potassium deficiency if lights not the issue. Back off the light a little or turn it down a little for a few days if the spread immediately stops upon reducing the light exposure thats your culprit. Check your ph and so long as it's in normal range potassium is likely not the problem. If ph is off adjust it and they should stop spreading the damage. However In the rare off chance your soil is actually deficient in potassium it would be a easy test for and fix as virtually all nutrient additives have some range of n p and (k)
