I had it up to 22inches since the lights turned on but that's still happening.
1. Why is the now middle plant unaffected by this?
2. Why has it only started now when they've been fine for 2 weeks at 18 inches?
3. Could it still be recovering from the 14inch away light and may take a few days?

I'll raise the light yet again to 25 inches and see if that makes a difference.

Edit.



Yeap, i've just raised it to 25 inches now.
I was thinking they might need time to recover from the light being at 14 inches...

How old are they? Id assume about 3-5 weeks old? I bet theyre running outa pot space, that and hot warm are the pots by the end of the cycle? Id wager theyre nearly or are root bound, 6l or 1.5 gallon is not very much at all. Especially in smart pots, roots are probably very prominant.

Hey, the one thats sagging is 4 weeks today and the other two are 3 weeks.
The pots are warm on the outside, just checked them now.
I transplanted them maybe a week and half ago from their starter pots into 6L pots.
There are quite a few roots coming out of the bottom of each of them, ill take some photos and upload them in a sec.

Photo is of the biggest plant and the one thats sagging.
Other two have roots like that but not as many.

All done, lights just turned off now.
I'll feed as soon as the lights turn on in 6 hours.
Hopefully this solves the problem.

light still too close for my liking id be moving that up another foot but i like more stretch in veg as its easier t scrog
ive always found my plants grow slower if lights close
id mount that carbon filter on the roof. them plants will grow over it soon plus it would remove heat better although you said heat is not a problem
by the end of that grow id expect your light to be at roof height for optimal light spread
will you be using more light in flower or just the 400w
400w should be enough for that space but more is always nice maybe a 600w max

Really? I could put it up a lot more but it says on all the charts along with people telling me anything over 18 inch and you start losing yield etc?
I can move the carbon filter up as it's on pully's but i find it makes the room cooler being down at canopy height for now, the temp above my light is cooler than where the filter is.
Nope, i'll just be using 400W but have a MH and HPS bulb so will obviously flip that over and will be scroging i think.
If i switch to a 600w it would be way too hot, i'd have to upgrade fan etc which would be more noise which i can't have.
400w Will cover my area nicely, and will do what i want it to do :)

True..
So when im in flower do i have it at 18 inches or?

EDIT:

Also the light probably looks close because i haven't adjusted it since i transplanted so the pots are obviously taller so they'll be about 5-6 inches too close!

in flower its better to keep light closer as keeping the light too far in flower will affect yield is still not go closer then 18 inches
in veg i find keeping the light high works better because you want the plant to stretch up in to the light id go 27 inches or 32 inches depending how much elongations you want between nodes

Fair call and makes sense.
I'll want them quite compact but still need them to stretch up a bit now to fill a screen that i'll add very soon.
HPS is apparently not as hot as MH so that'll help with the plant being closer to the light.
I need to get something to keep the pots out of their trays so they don't sit in water when i feed cause i won't be able to lift them out once they're in the screen.

EDIT: Thanks to everyone that give their opinions, hopefully between them almost being root bound and light height etc i'll have it sorted now. Will update later.

Ah man I didn’t think of root issues! I assumed no root issues since you had fabric pots. Strange, I learned something new today. I’m gonna keep a close eye on this, we can all learn something

They were in plastic pots, but are now in fabric pots that i'll finish them in (5gal).
I don't know if they were root bound, but the big one had a huge amount of roots.
Reckon a cake cooling rack under each one in the trays would be good so they aren't sitting in runoff?
Just worried with possible rust, but they're stainless or coated ones im looking at.

Keep us posted, fabric pots help a shit ton. Where are the lights currently at?

Well they aren't as bad this morning but still doing the same thing, sagging and all 3 kinda did it.
No where near to the extent as they were yesterday but i have to remember i transplanted yesterday.
Had the light at 23 inches and still sagged a bit, the part i can't understand is why they had no problems before now?
I'm starting to think it's heat/humidity, temps don't get above 28 (82 Fahrenheit) in the actual room, the probe thats under a leaf at canopy height never went over 27 so can't be heat? Humidity can get as low as 30 though.. during dark it slowly rises till it hits 60-70rh.
Updated picture from this morning.

just a suggestion it will not help the saggy leaves but id cut off the leaves that are touching your medium as that could make the plant sick or them leaves to get moldy and attract bugs

Okay, thanks ill do that when the lights come back on..there's just a couple underneath at the bottom that are touching.
I feel a bit better that they aren't sagged really bad tonight but i feel like they might still be recovering from the light at 14 inches.

I'll see what they're like tmrw morning, i've move the light up to 25inches now too.
If they still do the same thing what do i do? I don't know what else i can do to bring up RH which could possibly be doing it.
They look healthy otherwise apart from the sagging in the last few hours of their light cycle.

some plant will just naturally sag because them leaves are big and ill take a week or two plants look nice regardless of the sag
