plants drooping under new lights

Hey there.
I just got 2 new 400w hps lights and Iput in two flowrering plants with the lights too close and it burned a couple nugs. I raised it a couple inches and still bburned.

Now I have enough height in there to not burn and I put a couple smaller vegging plants in today to give em a little boost on light because my veg area is messed up and only getting side lighting at the moment.

The plants that are having problems is the vegging plants. Granted they are root bound. But they are drooping real bad like they are super dryed out but they aren't. Temps are a bit high at around 85f but my plants have gotten used to high temps and they aren't really any higher than before the lights.

Any one else had issues switching light power or spectrums?

Put your hand at the top of the plants,,,,,,is it hot? That's what the plant feels too.
Move the light to at least 18" from the top of the plants.

The "spectrum" change means nothing to this problem.
85F and no Co2? Too hot! Cool the area!

Ok man you should read posts before replying.

Already said I got the lights high enough for the taller plants so how would it be too close for a plant that sits a whole 14 incheslower. Light is lotterally like 3+ft away from the plants its affecting.

Also i obviously stated that I knew about the high temps and that my plants are used to high temps and dont droop under higher temps before I switched my areas arround.

Dude your tone is gonna get you no help. There are already way too many snippy biches on these forums for people to deal with civilly. You should be gracious for any help you get instead of shutting people down when they try to assist you. We work with limited information most of the time, so it takes grace and real conversational exchange to find solutions. If you aren't willing to work with people that try to offer help, then don't ask for help... Obviously.

Ok id like to revise what is going on now because it seems the three small rootbound plants aren't the only ones that do this.

In my new flower area with the new lights rhere is two flowering plants which were under a 250w mh and some CFL's. Those made the switxh to.hps fine eventhough iI burned them twice with the lights.

I put three small rootbound plants in for a while to give them light while I set my veg lights back up (I switched my veg and flower areas around). Three hours later all the vegging plants were drooping straigjt down at 85 degrees even though they were used to temps in the low 80s. So I obviouslytook them out. The veveg area now is just in the corner of a room with panda film around it and sits at around 70-75 when my hps ballasts are running. These small plants did not recover well over night.

So its been three days and the small plants are slowlyputting out new growth and have been transplanted. But iI put a different older not rootbound plant in this morning and within an hour its drooping a bit already. I got the flower room temps down to 78-81 ish so I dont thinknits too hot.

So rhe question is why are these lights making vegging plants so sickly and doing perfectly fine with an already flowering plant?

How about a picture or two? I must say this one is a bit of a mystery. I've not had a plant ever wilt in response to a light.
Three days post transplant and no improvement?

It almost sounds like some kind of transplant shock. Are you sure you didn't mess with the roots of those plants too much?

And those pics are after 3 days recovery since droop issue.

I'm starting to think that these strains just may be very picky once they get used to temps? (Master kush and strawberry cough) this is the most temp fluctuation ive ever had to give them and they had to only have enough light to keep.photo period for two days because of me doing work switching around areas then having a couple delays. But after seeing another vegging plant go in and droop in under a couple hours with temps at 81 is confusing me..

The pots are on the floor, but at the same time when ive been checking for coldest temps in that area ive been putting the meter on the floor and out of the light but still close to the plants. So I dont see why the pots would be getting colder than that.

And in the flower room I dont think it would be too cold either. As for being too wet they have been drinking water fine up until.they wewent under those lights. And ive only been watering when they get real dry, to the point when they feel almost empty when picked up

No. When I did the transplant they were under the t5s again.

Humm... I like to transplant in dim lit areas because roots don't like light... Actually I did a water change the other day with a Deepwater culture of kale that I have outside in natural light.One of the plants out of eight had roots exposed to high noon sunlight and it has flopped over and is slow to recover.i'm betting it's some kind of shock. But I wouldn't know what the recovery time is.if it is a root problem. Assume you have lost some function and be careful with the water

Oh I thought you meant if they were in dim light afterbthe transplant.. the space where I actually transplanted was just normal house lighting.

Just had a thought

Think that 4-5 days is enough for a plant to get used to temps in 70s? If so could putting them in the closet with 80 temps and a lot more lumens shock them real bad?

Never really heard of it but just a thought.

*edit: odly though if this were true than.ii probably would have seen similar stress going from temps in the 80s down to the low 70s no?

I wouldn't think it wasn't possible... A consistent and stable environment is desirable, but temperature fluctuations to greater degrees happen in nature... So unless they are breading that adaptability out unintentionally or otherwise I would think it is unlikely that it is your problem.
