Droopy Female

Any ideas what is wrong with this thing? I'm using Fox Farm trio at half strength, once per week following the feeding schedule. I checked the PH and it was good, moisture was perfect, and the plant has 300 real watts all to itself. It's always looked awesome, but since pistils started forming, the plant has been getting droopy. Is this normal for flowering?

I've also noticed some nute burn on 2-3 leaves, but the rest have normal color. Purple is increasing on the stems as well.

Thanks for the input

is she getting fresh air?

Actually, now that I think about it, I had the fan off for most of the day (forgot to turn it on), and also recently, I've cut fresh air a bit in favor of sealing off some light leaks in the dark room.

I think you may be on to something Also, I added 2 more 65W lights and removed another plant. So I've also nearly tripled the amount of light/heat she's been getting over the past few days.

I wonder if it is heat stress?

also after closer inspection i noticed floor temp is at 81 might want to check overall room temps

As an update to this thread.....

Examining the plant further, I noticed she had multiple leaves that were showing nute burn (N claw and yellowing of some leaf tips). I found this very odd since I've been going super easy on the nutes (once per week, half the recommended strength). I gave her a huge dose of water to flush, and she's perking up very nicely.

I'm learning that this sativa is a finicky one, and that not all plants can handle nutes.

IMO- Your plant looks good, I wouldn't worry about it. Your doing a good job.
You have long slender leaves from this strain there going to droop a little bit.

Good Luck on Your Grow.

Thanks, topfuel! First grow, so I wasn't sure what to expect. Cant wait till harvest.
