ILGM Auto NL Indoor Grow (COVID-19 era)

Thursday, May 7 (Day 42, first day of Week 7 total, start of 3rd week of flowering) - Plants seem in much better shape than a couple of weeks ago. They were struggling then, wilting/droopy. In retrospect I think it was from overwatering. I had been concerned about pH because my tap water tests at 8+. I haven't been testing alkalinity but the tap water in this area is considered hard to very-hard. I bought a decent pH meter and after calibrating I've been able to be more precise. The soil mixture run off seemed okay pH-wise, actually. I'd flushed with FloraKlean and the run-off was ~6.5. At that time I also added more perlite into the pot, hand mixing it in, gently to try not to disturb roots too much. Leaves got pretty funky after that. I let the soil mixture get on the dry side (mostly determined by weight of pots but also sticking my finger a couple inches into the soil) and have watered them twice since then with GH nutrients, trying to be conservative with amount of water and ensure first couple of inches of medium dry before watering again. This is my 3rd grow over a period of 5-10 years if I am remembering correctly. The one I did a couple of years ago was the second one and the grow medium was not soil but coco coir and perlite. I think the watering needs of that grow-- basically daily to run off each time-- set my expectations in a way that contributed to water-logging this soil grow. Also complicating matters was my focus on setting up Blumat Tropf irrigation the first few weeks. Friday, May 8 (Day 43) - Just checking on them after the second watering yesterday. Before that water I'd trimmed leaves that looked like they needed it from each plant, meaning if they looked wilty or yellowing. Today they seem pretty good. Well into flowering. A couple of the plants appear to be developing multiple colas. Since I lost track of labeling/numbering the plants I can't be sure if those were the two I'd topped or not. When worried about the plants surviving I had also stopped trying to LST them. I guess my 'Grow Technique' now would be considered Defoliation but I'm not trying to lollipop or anything that methodical. Another aside that I may have mentioned already in the comments but a week or two ago I turned my lights timer from On to Auto which means the plants are getting 4 (or 6?) hours dark now. The outlet and timer are kind of shoved between the wall and the tent so it's not easy to look and that detail isn't important to me right now. I'll double-check at post at some point what the light cycle is. Pretty sure I set it to be dark from 2am to 6am... I adjusted the GrowDiary Conditions above on May 9 which is when I'm updating. Height of plant is estimated. Water quantity is calculated as follows: ~2 gallons spread out among 7 plants with 3 days in between watering. (2 / 7) / 3 = gallons/24-hr water volume per plant. Day 45 (May 10) Sunday - Happy Mother’s Day in United States or wherever else it’s celebrated. Just trying not to fuss with plants. Still another day or two before time to water again. Maybe I can increase nutrients a bit. Day 46 - lights-off pics Day 47 - cut off sickly leaves and watered 5 of 7 plants. Partly because I wanted to see if much different the next day. Day 48 - Not much different it seems. I finished watering. Took some pics from above each plant.
