Why are the leaves drooping only on the tops?

What the other 2 said could have been correct. But in your comment you have said your run off was ph 5 so that's your problem. Your medium is at the wrong ph. You need to get that within range and your plant will bounce back.

@DasBoof . I found out that my soil pH was around 5. Just I corrected it and gave her an early feed of Bio bloom (3ml / L) and Top max (1ml/ L). @KushGANG. I have both intake and 4" extraction fan with filter, two clip fans blowing around the plant. Temp: 24-25C, RH 40%-60%. Like I said to @DasBoof, it might have been a pH problem since it was really low (5). Let me know what you guys think...

Hey there Gnugs, so the droopiness could have been caused by the watering, but most probably it's a root zone issue. that's because something developed down there . so what you want to do is to fix the problem roots. This you can do by breaking them down . The best thing to use for you do to that is Top Max. Top Max is just humic acid . Go full strength with top max for a week to ten days and it should fix your issue completely and quickly . Hope this helps ! 🚀

Hello Gnugs87 . first i can see your plant needs more nitrogen you have a deficience of that. After if you plant is still droopy it may be because you have a problem with your environment conditions. Do you have an intake ? An extration ? A fan in your tent ? Maybe you don't have enough air circulation and your plant reacts like this. Give news please. Bye
