looks like bad ph in soil and water, and over watering. also pull off on how close your lights are, and take some lights off, cus your temps are high my brother, even do a homemade c02 to help with the heat
Yellow tips from bottom up are usually an indication of over fert. Also, DO3SHA is right, your thermometer in the pic says 86. Too warm. Any way to ventilate the area more? Its not that you cant grow and harvest with that temp, its just that you likely wont get your plants best and maximum yield. Nice plant though.
My suggestion would be to back off the amount of fert you used on your last watering when your lady is thirsty, and see how she responds. They ALWAYS tell you how they feel, one way or the other. What is the strain anyways? Looks like a hybrid and a little more Sativiaish than Indica. Check out the chart below, hope it helps.

"I used to smoke marijuana. But I'll tell you something: I would only smoke it in the late evening. Oh, occasionally the early evening, but usually the late evening - or the mid-evening. Just the early evening, midevening and late evening. Occasionally, early afternoon, early midafternoon, or perhaps the late-midafternoon. Oh, sometimes the early-mid-late-early morning. . . . But never at dusk." Steve Martin
