Overfertilizing, too much sun or not enough water. Best if you can grow it indoors under growlights (more control). Do not fertilize untill you have 18″ or so height then fertilize very lightly. If you are growing indoors keep your plant bolow 80 degrees (if you can) and you get higher THC content.
Cannot produce chlorophyll due to a Nitrogen deficiency.
I was growing indoors and the same thing happened to mine, but the plants came out fine. Couldn’t tell you the long run results though because at 3 feet tall my stupid cat ate the tops of the plants off.
