White Widow Autos (first-time grower)

This week went OK. The Luvcosy PH meter is now giving readings up to 8.0 after giving readings as low as 5.1 last week, so I have given up on buying PH meters. I moved the 15W LED light from an overhead angle to horizontal to get to the "hard to reach" places since I didn't really do LST. New light also makes it hard to keep temperature at 72, as it's usually 74-75 now. Gave the plants molasses for the first time in 2-3 weeks. Plants 1&2 got too close to the light (yellowing), so I keep moving the light up. Grew from 6" to 10" in one week! Smell is there but barely noticeable. Plant 1: Pre-flower started with white pistils. Showed "the claw" 2-3 days ago which I assume is too much nitrogen, so I will wait another day to feed. Reaching for the horizontal light which is good. Plant 2: Tried some LST, although it might have been a little late. I don't think I did it well and don't know if it will do any better than the sideways LED. Plant 3: Continues to grow and produce new leaves, so I'm keeping this experiment going as long as it continues to grow. Secondary stem is much thicker than the main stem. Plant 4: Yellowed due to too much light, and it improved after I moved it away from the light.
