Hi. This is my first grow and i have thes brown spots on my leaves. Not sure if it is nutrient burn or i had my spectrum king sk400 too low. I am using ocean forest soil and fox farm nutes. I only used the nutes a week ago 1 time. I noticed spots on the leaves and quit using. I just transplanted into 7 gallon pot also. Any help would be great. I did raise the light up quite abit.
