I just got done reading through your thread and felt compelled to respond. Flower that mother and get rid of her. That girl has been suffering her whole life, release her spirit already. When you get your check, get a digital ph tester. You can find a hannah checker for around thirty bucks on the internet. Nice job on revegging her and I do think you may get an ounce, so let her go after she does and find a new mother. Don't use your own soil again, ever. It's rather expensive for me to use foxfarm soils exclusively, so I also buy a big bag of Scott's Premium container potting soil and a bag of miracle grows organic, both from home depot. I use ocean forest and happy frog from foxfarm and I mix some of each altogether throw in some extra worm castings and perlite and she's ready to be put into containers. I use two and three gallon waste paper baskets from walmart, less than three bucks each and can be used over and over.
Start over, get rid of anything you created in the line of soil. Get a ph meter. I ph my mixes to 6.5 until flowering and then lower it to 6.3. As one astute poster stated, the soil will make it rise over time. I end up right around seven when done. Your plants all appear to be stretching, low nitrogen and your lights are to far away is my guess, plus the death soil you created. Now look at the bright side, you learned something and I'm pretty sure you won't go that route again. Light is the plants food, everything else is additives. Keep your lights as close as possible without burning your plants. The hand test.
