smoke24answered grow question 4 years ago That is from your lights. I have the same light, and the girls don't like it that close. I bet that plant is the tallest one you have....and if so she has gotten way closer to the light than your other plants. If you raise the light to 22 inches your problem will stop, however you may need to lift your other plants up so that all the canopies are on the same level. But they look pretty good, grow is doing nicely. Keep up the good work.
