Liberty Haze - DWC - 7+yr old seed

**Week of Wednesday 5/12/2021 - Tuesday 5/18/2021** This last week I've had a lot of personal stuff going on (or it's come to a climax this last week, but been the last month), and haven't had as much time to dedicate to documentation. I can barely keep my head above water with how much shit I've got on my plate. Anyways... I didn't take pictures every day, which is a bummer. I also did not do a water change this morning. The reason being that I've ordered a battery powered liquid transfer pump because I'm tearing shit up every time I do a water change. I should be getting the pump today so I will be doing a water change this evening....I hope. My PH has been dropping pretty heavily for two reasons I believe: 1) The first part of the week my solution was way to hot. The plant is responding better (PH-fluctuation-wise) in the low 600 ppm range. 2) The plant is pounding down at least 1 gallon every 24 hours. I should be doing a water change closer to every 4 days instead of 7. Heck I'm not adding quite 4 gallons total with the size of the root ball (which I think may be part of why my starting ppm was high) I'm still seeing the tip burn/nute-lockout/whatever very slowly progressing. This may just be the natural progression and nothing I'm doing wrong. However, I do believe the PH issues outlined above could be contributing. Looking at picture comparisons in the last week she is still very slowly bulking up. I'm not sure her buds are going to get quite to what I was hoping for so far. All trichomes are clear, and hardly any red pistols so I'm thinking she is going to go out to 10 weeks in flower. This means I've got 2 more weeks left, approximately. I'm hoping by doing more frequent water changes (without having to move the ScrOG) will help the situation. I added some "light's on" pictures as a comparison to "light's off." You can see the leaf damage a little better.
