Hey Power.P sorry for just now getting back to you. The drooping leaves isn't drooping from overwatering. It is N toxicity, this late in flowering your plant doesn't need any N. The problem is, you have a pretty good bit of natural ferts in the soil and the nutes you are using had N in at as well. Also, it doesn't have enough P&K to do any good. The yellowing leaves are normal in this stage. Expect that over the next few weeks. You gotta get some P&K in the plant though and you could use a flush to get some of that nitrogen out. That looks like a 4-8 liter air pot, if so, flush it with about 10-15 liters of ph'd water and then feed with some P/K. A pretty good amount, I would go full strength as late as it is and as little as she is getting. From now on, if I don't get back to you within a day PM me with the link to your thread. I forget throughout the day everyone I have helped and if they don't say anything then I don't normally remember to check back. Let me know how that does once you get her settled back down. After you flush, you should see a difference in those leaves within 24-48 hours tops.
