First Timer - Amnesia Haze Auto

Dec 1 - Day 56 Pot bone dry, very light. She's just barely droopy. Hope I'm catching her at a good time. Mixed 1/4 tsp better-gro, 1/4 tsp bloom, into 2-liter (~half gallon). Fed with almost the entirety, which she seemed to drink right up. There was considerable runoff, for a change, that was absorbed within an hour. Sprayed with a bit of rainwater and rotated. Also removed the first training wires which thankfully resulted in no movement from the plant, so I guess that bit of training was successful. This gave me better access to her bottom portion, which allowed me to pinch a few yellowing / unproductive leaves for the first time. Seems healthy to me! Dec 2 - Day 57 Just resting. Rotated. Dec 3 - Day 58 Pot light but I think I'm going to give her another day to have a full dry-out. Mixed water and nutes for next feeding (1/4tsp Veg, 1/4tsp Bloom, 2L evaporated water) and stored in tent for temp stability. Rotated. Dec 4 - Day 59 Fed with ~2L solution that was described yesterday. Rotated. Dec 5 - Day 60 Troublingly, she became quite droopy overnight. Water was PH'd and room temp. I'm not really sure of the cause and unfortunately, I didn't take any pics. I feel like it can't have been too soon for watering. Perhaps it was simply too much volume or ferts are too strong (even though they weren't recently increased). Placed a towel under the pot and pointed the fan at it, making sure not to cause too much leaf movement from the airflow. About 10-12 hours later, after lights on at 4:20, she seems better so towel was removed. She was rotated and will let her rest. Dec 6 - Day 61 She seems to be progressing well. I guess this is the flowering stretch I keep hearing about! Dec 7 - Day 62 Pot feels almost empty/dry. Mixed 2L evap'd water with 1/4 tsp veg and 1/4 tsp bloom ferts and fed with 1L of the solution at lights-on. This is less volume than last time as the amount of water and/or nutes seemed to shock her last time. Hopefully, that's not the case again. Also, I know I've written this before, but I think the next feeding should probably include bloom ferts only, or at least at a majority ratio. 2 hours later, she's drooping after feeding... again. I'm confident she'll bounce back in 12-18 hours like last time, but it's still quite troubling. Going to post a question for ideas. 12 hours later, she is back to 'normal' (see pics). However, I'll definitely be following some of the advice from the kind folks that answered my posted question. The medium seems to have proven itself to be too dense. This is causing her to suffocate when watered. I was aware and warned of this based on the initial composition ratios, a novice mistake, but confirmation helps the lesson be learned i suppose. My 2nd grow currently has about 2x more perlite and mostly consists of coco coir, which she'll hopefully benefit from. Additionally, I'll be flushing and providing less N in the future at this stage in her development. Thanks again to those who responded and commented. It's sincerely appreciated!
