First Grow White Skunk Whats wrong?

HI
I have just entered the 4th week of flowering my White skunk plants in soil. Iâ??m using a 400 watt hps on the 12/12 cycle. Iâ??m using the Grotek Nutrients and Iâ??m following the directions very carefully. My plants seem to need watering every two days.
Two of my plants seem to be growing well. However the plant Iâ??m having the issues with is the tallest of the three and the leaves from the buds are long and narrow and the leaves are pointing down. The good plants leaves are spread out and pointing out straight. Iâ??m wondering is my plant in shock due to my grow room getting extremely hot one day.
I have also noticed the bigger leaves which I think are called the fan leaves have changed colour on all three plants, slightly yellow.
Thanks in advance for any help you can provide. I have attached two photos

Are you by chance feeding with every watering...? If so...discontinue that practice, and follow manufacturers directions. Plain, properly ph'd water between feeding days, but let the pot dry-out a tad between waterings. (don't keep the soil saturated)

I live in the Desert, and almost every day I'll add about a quart and a half of properly ph'd water to my 5 gallon nursery pots. (mature plants) But then, normal room temp in my flower shed is around 95.

If that isn't the problem, you'll need to fill out the troubleshooting form. The link is in my signature. Copy-n-paste it here, and answer all that you can.
