Problem with plant - LED COBS/COCO/GH FLORA

Hi all, as the title states I'm having issues with my plant. The plant looks limp/sad and I'm not 100% sure why. Any help would be appreciated!

Some info:

• As of this post it's 22 Days since the sprout surfaced
• Barneys Farm G13 Haze(Fem)
• 250w(from the wall) LED COBS(Bridgelux Vero 29's in 3000k and 4000k)
• Coco coir/perlite mix(about 60% coco and 40% perlite)
• General Hydroponics Flora Trio + CalMag
• Using GWE's custom coco/gh schedule http://www.growweedeasy.com/sites/growweedeasy.com/files/coco-coir-flora-series-schedule.pdf
• Water always ph'ed to 5.8
• Temps have fluxuated alot. Averages are 67-80F
• Topped once
• Some LST

All the leaves look wrinkly/limp and overall unhealthy. Some of the leaves have very minor spotting and one or two leaves have holes in them.

is it getting fresh air and good air circulation?

I do have a small fan exhaust fan in the ceiling but it's only using a 120mm fan. I also have a pretty powerful little fan on the floor that is aimed upwards at an angle to have airflow. This is inside a closet and pulls air from my room, my closet door when closed does not fit perfectly in the frame so there are gaps almost all the way around the door.

Since my original post and now spots have started appearing on some leafs and from googling around looks like it's due to ph fluxuation. I have some ph calibration liquid in the mail now.

I'd still love some input on what this could be, heres some updated pics.

I have one of the same growing, and my g-13 haze is a very light feeder.
If i go over 1/4 recommended strength with the nutes, she doesnt like it.

This is mine at roughly the same age. I had problems early on that stunted it a bit. Mainlined and tortured a bit.

Drinking wine from the bottle and huffing pledge, sounds like a relaxing Saturday night!

The lights are about to flip back on and I'm anxious to see if they have improved overnight.

I've followed the gew coco schedule to the t, but I have a feeling my ph meter got messed with or lost calibration. I hope my plant's looking better today.
