2 Candy Kush/1 Blue Dream/1 White Widow

Plants look great. Have been growing for five years and somehow I just realized I've been making a mistake for a long time. Somewhere along the line I picked up watering with 77 degree water. First time watering with 68 degree water. Excited to see results. White widow is the slow grower, still a little prayer like but no way she's getting too much light. Not sure what's going on but she still look good. Blue dream upper right hand corner. Candy kush both up front. Considering more light for the areas not directly under the bulb. Not sure what yet....thinking of ideas. open to suggestions.
