Was wondering if anybody could tell me what kind of deficiency this is. It's only showing up on these 4 same cloned plants. Yellowing streaks and blotchiness but what has me stumped is its showing up at the top first and working it's way down. If it were nitrogen deficient then the yellowing would start at the bottom. Notice in the last pic theirs a leaf that's split down the center vein, green on one side and yellow on the other.
