Droopy leaves

[BigB6]

Problem: Droopy leaves

Medium/grow method: Bio buzz light mix

Feed: and supplements used: Biobizz full range except bio heaven, also using a little bud candy. All at half or less strength.

water source: Tap, water left for a couple of days before use

Strain/age: Expert seeds glueberry, week 5

light used: LUMATEC AURORA 315w CMH

Climate: Daytime around 24oC nighttime around 18oc, humidity at the moment around 60-70

Additional info: Thank you all that respond, we all owe you a dept of gratitude. This is my first time growing with cmh. I water every 2 days or when needed. Nutes with water every time. Usually 2&1/2 liters per plant. The pot is 12 LTR with about 10 LTR of soil. This droopiness is extremely bad 2 hrs before lights out but doesn't pick up much during the day. The soil went dry on one occasion few days ago when I wasn't able to water. Since then it's like this. Also I haven't been watering until 20% run off this time.

Some of that drooping before lights out is a normal thing, though I'm not sure what's behind it... many of my plants do this as well, inside, outside both....
A bad dry-out can damage roots, deform the petioles enough that they never really shape right again,... plus water uptake may be lessened due to roots damage...

If your Biobizz lite got dry, the peat can become hydrophobic. This can allow dry pockets to remain in the pot even though you are watering. Add a surfactant to your fertigation. I like yucca powder but even a drop of soap will work (soap not detergent) Peat is like hydro in many ways and you should always fertigate to ~15% run-off.

The plant is pretty far into flower but a foliar feed of fulvic acid, kelp, Aminos , B-Vitmins, and yucca powder can be very therapeutic if you can avoid the flowers. This is Harley Smiths tonic.
