Correct:thumbsup:

Light and heat stress can cause bleaching in plants. The yellowing is due to the chlorophyl that is leaching out of the leaf/bud. When this happens, the "bleached" leaves/buds are unable to photosynthesize correctly. The heat stress comes in when the lamp is too close and their is not enough air exchange. Might want to raise your lights a bit or up your air exchange rate or both....... Hope this helps......

Happy Growing!!!
