First-time grower here. About a month ago, I switched to 12/12 and now my leaves are starting to turn yellow around the bottom and get a different shade of green in the middle. Some of the well-colored leaves look “burnt” around the edges. I can’t tell if I’m overwatering, under adding nutrients, have a nitrogen deficiency, or something else. The uppermost leaves seem pointed towards the light like they are doing well, but it seems a bit too early for all the leaves to be yellowing to me. Any advice is appreciated. I will try to post some pictures if I can figure it out.
