Amnesia Haze Auto

Going into week 3 I have noticed a slight smell coming from the plant, she is staying short but has significant undergrowth. From my past experiences with Auto's I can tell she is nearing flower and It appears that she may have started to grow some pistils. I will take pictures if I am able to. I may move my lights up just a bit to encourage a little more vertical growth, before the flowering stretch. My goals this week are to perform some LST before getting too far into flowering and perhaps do a feeding or two with Recharge, in an attempt to add some pep to her step. RH seems to be under control for the most part but I am seeing a spike when the lights go out to mid 60%'s. I have not found any additional Gnats, for which I am grateful. I am aiming for a watering PH around 6.0 @ room temp, while upping COCO A & B by .5 ml per gallon.
