My babies are finishing their first week of flowering, and they are exploding. But due to circumstances, I had to shut the light off for 36 hours strait, they are now back on the light (hps). However, some of the leaves have taken on a yellow-green color. could that be due to the light change? will they recover now that the light is back on? Is there anything I can do to help the recovery? Help would be appreciated, thanks.
