Droopy plant before and after watering + unidentified deficency

[t0m420]

Hi
My skunk xl from royal queen seeds started to get droopy apparently out of nothing
She is droopy before and after watering...so I don't think it can be over/underwatering...
I am using:
biobizz bio-grow
biobizz all-mix
Optic 2 led growlight at 18" at 20/4 light
shedule
Day temp is on 23/24 degrees
Night temp is on 17/18 degrees
Humidity is around 40%
The plant is on end of 4th week of veg.
Can someone help me?

Hi t0...
what type of medium are you in?
how often and how much are you watering?
what are you pHing your water at?
Do those pots have any holes in the bottom?
What size pots are they?
What strength nutes are you giving it? Full, half, quarter dose of manufacturer recommendations

Soil: biobizz all mix

I weight the pot to understand if they are dry or not... if they are...I water

I ph water around 6.5

Yes they have holes on the bottom

Half strength

The pots are 4 liters

OK good. Are you seeing any water coming out the bottom when you water? Is it possible the roots are stopping the drainage?
The pots are probably 1 gallon pots and need to be bigger. Your roots are probably bound and need oxygen. Can you get some cheap fabric pots, minimum 3gal, better if you get 5gal and up-pot.
Fabric pots you can weigh and feel more effectively for watering amongst other benefits.

I had already checked the roots...but no rootbound...they are barely visible around the soil brick...

Well my feeling is the pots are too small and uppotting them would help. Others may chime in but the fact they are droopy all the time leads me to believe their is no drainage or too small a pot.

@Emilya is a wealth of knowledge. Perhaps she can help out when she has some time.

 

[Emilya Green]

so far not enough clues... but let me dig a bit further. What is the duration of your wet/dry cycle, ie the number of days between watering? This time for the plants to drain the water should steadily decrease as the roots get stronger, until she gets to being able to drain that container in 24 hours or so, and this would indicate the need to up-pot.
Have you noticed the time between waterings change, stagnate or get longer?

Thanks for stopping by Emilya...

Glad to help! I can't stand idly by while plants are suffering! Let's figure this out!

 

[MrSauga]

Yes and I truly appreciate it! I've seen some of the threads lately and glad you still came by.

No one is chasing me off MrSauga. I will continue to defend basic gardening methods and practices no matter who gets all in a tither over it.

Do they droop and then recover a few hours after watering?

Some strains are just sensitive and simply express themselves more. I’ve worked with Chem Dawg and certain OG strains that would drop after a feeding and then pray a few hours later, while other strains getting the exact same treatment would be just fine.

Are you using the optic 2, 3 rd gen? You are running at 18" now? I just looked at your lights specs. If I'm looking at the right one... It says you are supposed to be running them at 24-36" in veg and 18-24" in full flower. So blasting them probably isn't helping them. Back your lights off first before you do anything drastic.

Sorry I meant 24...

Nope...they are droopy before and after watering almost at the same way

So you never have said how often you water... you said you weigh them, but we don't know if you are accepting a little bit of water weight or none at all. All of your symptoms point to the roots... the constant drooping means the plants cant develop enough water pressure in the trunk to raise those leaves up to be able to track the sun across the sky as a healthy plant would do. I am still suspecting that you are watering too often because if you were rootbound you would be seeing other damage on the lower leaves. I suspect that your very lowest roots are in trouble because they are constantly under water and as a result have partially shut down.
