So my leaves have started wilting a bit. It got cold last night so I'm hoping it's just the cold but the temperature never dropped below 70°F. Here's some more quick, relevant info.

STRAIN: Gorilla Glue Auto (22 days old)

AIR TEMP: 70°F (back up to 78°F now)

RESERVOIR TEMP: 62°F (back up to 69°F now)

NUTES: 785ppm (was around 900ppm a week ago, the reservoir has not been topped off in that time, weird? She has only taken in maybe 3L of water in that time).

pH: 5.8-6.0

Height: 5.5"

Light: 300W LED about 21" from canopy (Mars Hydro TSW 2000)

PROBLEM: wilting from the top down, new growth affected the most

OTHER: She first showed her sex about 5 days ago. Calyxes popping up rapidly now. She is still on veg nutes as she hasn't really entered the stretch yet.

The light makes her look lighter green than she actually is, could have N deficiency, but I don't believe so.

My gut instinct is to let her go and see if she recovers. If it doesn't get better I will just change the res (using RO water).

Thoughts?

Top ‐ down, maybe she needs more micros? Roots look very healthy still... I can add more pictures if needed.

Turned out she was unable to take the ppms I was giving her. I reeled them back to 700 and she's doing beautifully.

Less is always best mate. Just follow the ppm. Keep it dropping a little from day to day and you're about as close to spot on as it gets.
If ppm drops more than like 10% each day then up the nutes by 50%.
Wait for the drop then repeat.
If ppm rises at all then just add water (+ calmag If r/o) untill it starts dropping.
