Drooping Fast and no change

i don't see overwatering. i see poor watering habits are likely as i look through weeks of diary. FFOF is hot soil. it can provide nutes for over a month. As i click through weeks you start feeding in week 4 or so and it quickly gets glossy leaves within a couple weeks. it's overfed, which cna also be exacerbated by the likely bad watering habits. water entire pot. never some volume you choose. that's hubris. Water until entire thing is wet.. a little runoff is fine. Wait for top 1" to dry and repeat. when you have a small plant and a large pot, lie you did early on, it's difficult to water properly. a small column is fine, but make sure it gets wet all the way to the bottom. you don't want it soaking wet for long periods of time, the plant should be able to drink up what you give within 3-5 days. a little longer is fine, if temporary, but long-term it's a really bad thing that will only invite pathogens in your root zone as well as suboptimal root growth - like disproportionate amount of superficial roots. scrolling through your diary i don't see that type of watering habit being used, but i could be wrong. pH is way too high if it is really 8. Soil slurries and runoff are not accurate measurements for rootzone. i see overfeeding and watering issues, though, so i'd get that worked out first, and if plant is healthy, that pH may be misleading or if still some residual issues, try to water with a lower pH water and it should correct the issue over time. usually pH issues cause many symptoms to be visible. i see a droopy plant with a hint of n-deficiency, but i'd get the irrigation process down first before reacting. not doing that right can cause all sorts of issues.
