Good Morning.
Droopy leaves occur with both under watering and overwatering. If the leaves feel dry and are slightly thin, it's under watering. If the leaves feel full and seem bloated, it's overwatering. Looking at your photos they seem to be puffy, so most likely you're using too much water, especially if your note about giving each plant a gallon each day is accurate.
Back to your data notes again, it sounds like you're continuing to feed with both the original all purpose fertilizer and have added the Bloom fertilizer as well? If so they're probably getting an excess of nitrogen. They're still growing and need some nitrogen for a few more weeks, but if you're giving both, that's causing the nutrient stress.
Also, I noted that you said you've been tucking some of your leaves to expose the lower buds, but I couldn't see any on your photos. This is a key time to get all those dozens of under-canopy buds exposed, so if you can't do it by tucking, you'll need to do some aggressive pruning.
If you haven't done so yet I suggest you Go to the GrowWeedEasy site and review their "Problems and Symptoms" link. They have an excellent section on diagnosing your problems complete with good photos. The last time I checked, Nebula Haze and her team had 500+ tutorials. Just be careful not to be one of those folks who go to WebMD and imagine they have every illness know to science!
All of this said, you've been doing a great job with your girls, and I love the methodical and detailed entries...librarians obviously are detail oriented!
You're doing great, so don't stress out and enjoy the ride.
Take Care.
