Leaves are drooping after swithing to new tent with more light

WeedLover487 · Mar 28, 2021

Hi all

Norther lights auto
42 days since seed
new tent is 3x2
2 quantum light boards, 120w each, 60 cm over the plant
lux read 25,000
lights schedule is 20:4
RO water + advance nutrition grow + cal mag
temperature is 25c
humidity is 50+-
Water PH usually 6-6.5 after adding nutes

Watering is perfect, no over and not under, for sure, 100%.

Day after the change, leaves are drooping and wilting.

Any idea why?
The lights shouldn't be an issue..
I read also that it may take few days to get use to the new lights? is it true?

Thanks

AN Grow? No Micros or Bloom?

Some cheap tents needs airing out for a couple of days before use, because they gas off or something. I remember reading about that years ago.

2 fans pointing directly at the plants? That can't be good... You wanna set them like this

If the lights are stronger it can take a few days to a week to get used to.

Try raising your light up a little give it a day or two and see if it gets better. If it does drop it down to a permanent height.

Rurumo · Mar 28, 2021

This can happen anytime you change lights, especially if the light is more powerful than what the plants are used to. Wattzzup is right, if the plants look stressed, you should raise the lights, let them recover, then lower them little by little each day until you hit your target height.

Read the directions

You use all three through out the whole grow. It's up to you to decide whether to go with 1/1/1 or alter the ratio.

I swapped from T5s to a 240w 4k led the plants went down hill rapidly, when I lifted the light to 30" they recovered.

Oldreefer · Mar 28, 2021

I often note a 'sag' in growth when moving plants from a veg area under 6500K to a flower area dominated by 3500-4000k...they adjust in a few days as long as they are healthy. Patience.

Star Dog · Mar 28, 2021

T5s

2/3 days with led

Thankfully they recover from it and and don't look like shit afterwards.

Good point, taken.
The fan is now direct to the far plant.

* Its very easy, wasn't an issue before, but your way is better.
Thanks!

I am working by this, can you please direct me to a better chart for autoflowers?
Everything I find for auto is based on Base Bloom product.. and I have Sensi grow A+B.

Lights distance up to 70cm ~ 28 inch.
I hope that will help them get better faster.

BTW - should I change to 18:6 instead of 20:4 or just wait?
Thanks

I’m seeing a lot of claimed ”expert” growers blaming their LED for their plants looking like shit

user error 100%

OP lift your lights up as high as they can get, get your temps to 82-85, get your RH to 60%+ and wait a couple days they'll be fine.

ComfortCreator · Mar 28, 2021

You are running autos, changes should be minimal. Temps in your new tent should be carefully monitored, it could be a bit cooler than before, not just a light issue.
