Strain is Super Lemon Haze by Greenhouse seeds. Medium is organic soil. Light is FL-1 from Volt grow 720W. Temp is 78 during the day 65 at night. RH is about 50%. Watered with black strap molasses and Gold Leaf nutes 5-4-9. also used a tea of worm castings, seabird guan, alfalfa meal and kelp meal. Recently just used Blue Planet cal mag. Lights are about 30” away. Watered every two days when dry. Did a slurry test, PH was 6.28 and PPM was 364. Plants were doing good, then started yellowing at the bottom and is moving to the top. Some purple streaking on the stems. Don’t know if that’s normal. First time grower, please help. Thanks

364 PPM in flowering is very low. I usually aim for 1000-1600 PPM when in flowering. The girls just may be hungry.
+1 for @mwhite9829 prognosis- that pH sounds good, PPM's low and I think I remember yellowing from bottom up as being a possible sign of nutrient deficiency-
Thank you!
The ppm seems a bit low for flower in my opinion. The leaf shapes droop like over water but tips curl up like under water or heat stress, weird. I definitely think you have a bit of phosphorus and potassium deficiency. The 6.2 h medium doesn't raise concern for me. If you can up nutrient intake a little it may help you out.
