How long ago did you transplant? If you did damage the roots they may be in transplant shock.
And how far above the older plants is the HPS?

Lets see if i can explain this one...

I've transplanted a few plants (they were getting to big! ) to some good recipients i have last week and till now everything was going OK.
Yesterday i received my 400W HPS son-t-agro and started using with some smaller plants and the transplanted ones.

The smaller plants love it ( you can see them with the leaves pointing to the light), and look very well; the transplanted ones by the contrary started to look dropy!
Hey, doesn't look like they're apretiating the HPS at all...

I've been noticing that after transplanting, when a good part of the roots are damage, plants seams to be confortable with not having a direct light over them; may this be a question of to much light????
The other thing i can think of is heat but the temperature is all right for the smaller ones.

Please remember they were looking good before exposure to HPS, so i'm not thinking in a soil question!
The distance is about 50 cm from the top off the plants.

If anyone can give me a hand...

lilbuddie...

The big ones were transplanted last week, the smallers 1.5 months ago.
There was a bit off damage in the root area but they we're doing fine, with no aparent signs off shock in the last 3 days, till...

It was a litle experience i was doing, so i left a group in a recipient, and transplanted the others to individual recepies to check the differences in growing.

The HPS is 50 cm away from the older ones top and 80 of the younger.
I'm only noticing problems with the older ( and bigger)ones!
Do you think it might be a question off the HPS being to close?

So I have been thinking about your problem and decided that I would look at the cause of the droopy leaves first before I look at at your explanation at all.

So some things that cause drooping leaves:
Too much water.
Lack of water.
To much heat or dank air.

These are the 3 most common causes for your problem. I'd let them dry out a bit before watering again and go easy on the ferts until they look like they start to recover. If the soil is humid (damp?) then you definitely let it dry out. Cut back watering to once a week.

Remember a plant dying from drying out is actually still much healthier than a dying plant from overwatering. Underwatering is MUCH easier to recover from than overwatering is....

Ok, so I flaked out and missed your obviuos statement regard light distance iun the first post sorry....

My initial thought was the new light was too close and too intense since the plants didn't grow with it they weren't used to it but that should be far enough away. Hmmm.... you could raise it about another foot and prop up the youngins so that they are not to far away when you do this.... What kind of light were you using before?

What about your watering schedule for the older ones? You haven't over watered them have you? And they are remaining green right? No yellowing or anything?

Sorry if i wasn't to clear about this but my english, sometimes, doesn't help...

I have been using SUNLIGHT, cause i live in a very sunny place !
With so many plants at home i was starting to feel like Tarzan...

No risk of overwarering (i think!), last month was rainy, till today, so i'm giving them water twice a week, just a bit. The soil is humid.

They remain green (some darker and some lighter but i'm growing different strains), with no yellow or brown, just very droppy ...

Anyway i've putted the HPS +20 cm far from the top and things looking good now.
The droppy ones (4) are getting sunlight till they recover and i'm going to concentrate in another big ones grup.

My guess is they couldn't take the light or the heat or both, but i would like to have your imput on it guys!

Lilbuddie - Thanks for your help (any more imputs?).

lilbuddie...

"...If the soil is humid (damp?) then you definitely let it dry out. Cut back watering to once a week..."

I'm going to follow your recomendation and
cut back watering to once a week but i don't think that would be the problem cause...

I've been growing this older plants for 6 months now and none off this happened with the others group.

I have 26 (femanle) plants now from seed after pulling males and 3 hermies out.
Every one off them is looking very well ( except the first group off 4) and the soil is in the same condition to all except i stoped fertilising the transplanted ones one week before transplanting (plain water).

Nothing of this is happening with the second group of 4 older ones ( this ones weren't transplanted).
So i assume that the plants are more sensitive to light / heat, after transplanting.

I've checked a few grow guides about lightning and the recomended distance from HPS to top plant should be bettwen 18 and 30 inches (if i'm not wrong that should be around 55/80 cm)
When i started the hps they were about 50 cm distance, now the're 80 cm distant and it looks the plants are liking...

Again thanks for your help!

lilbuddie...

First of all CONGRATULATIONS!
Very good looking plant !
Hope mines to look the same later on...

If you need any help with photoshop, please drop me a line.

Back to business...

I've putted a vent to move some air around the room, pulling temperature down.

Till this problem is solved, i'll feed the 4 dropy ones with plain water once a week as you said, and i will post about their condition here once a day.

Today the dropy ones are looking stable, no difference from what i notice yesterday.
At least they're not looking worst!
They are taking a good amount off sunlight,
no HPS for this ones till they look better.

The second group of big ones is stable to,
this is day 2 of HPS for this ones, 12/12.
HPS is 80 cm from the plants.

I've changed all plants (yesterday), except this ones to sunlight, at least till i understand what is going on...

Well, it's just what I think. If anyone else thinks I'm in err maybe they'll post thier opinion. Hey we all make mistakes and learn from them

I'd wait until the top 1" or so of soil was dried out at least.

Once they get used to the light you can start to move the light back down in increments til you find the right distance from them.

And keep me posted on their condition ...

Today's report...
I didn't post yesterday cause i wanted to have some real new detail to report.

The droppy ones are still stable, no yellows/browns, just very droppy leaves!
6th day now and a detail is punching my eyes now... Leaves look like they're drying !
This are the ones that were exposed to HPS 50cm for 2 days off 12/12.

Second group of big ones are changing a bit...
4th day off HPS, i've changed the lights to 18/6, don't think there's a good condition for flowering.
Even if their condition is better than the first group, leaves are getting the droppy/dry look ( it looks like the plants are loosing water).

Changed the distance to 100cm from the plants, i'm not getting this, things still not looking good for every plant that was exposed to HPS for more than 24 hours.
Every other plant is doing allright (just sunlight)
