Plants not looking great

Had them under a wee led light got off amazon..wee weapon gerylove
But got my new light ..repotted them the same day..went a day without an extractor fan got warm in there ..
Stressed the plants out ones went yellow
Do you think they will recover they are only small
Have my light on aboit 50 percent

I have an app to measure the light umols

they look a little dry

Agree with above. They look dry. Possibly hungry as well. What medium are they in?

50% and how close? I would definitely try backing the light up a bit as well.

They definitely look pretty dry. What media are you growing in? How often are they fed/watered?

On top if what others are asking, how warm is warm?

It got up to about 26 degrees with no extractor fan running,
They only got repotted so they don't need watered yet
I got the extractor running noe its lovely in thier now 23 degrees
Lights 20 inches away on 50 percent
Phone apps saying 500 umols
This is my first time doing led so seeking out on all the geek stuff like umols

Top of the soil has dried out bit
But they are heavy to lift they don't need watered
Will I spray the top of the soil keep that wet
Never had yellow plants on high pressure sodiums was always easy

One other thing I'm looking out for but haven't seen any
Is the little flies
Last time I grew I got flies in one pot
Kept on top of them but was killing 1 or 2 everyday
Hoovered the top of the soil and all with a vacuum cleaner

Relative humidity?

30 odds now
Not sure what it was prob about 60 odds with no extractor
It was warm with the heat build up
I wouldnt 100 percent put my faith in the phone app for the light measuring or the wee thermometer for the temp and humidity tbh

23 C is too cool for plants under LED. Ideal is between 25 and 29 C. Also, 30 rH is very low for verging plants. You are pretty far outside optimal VPD for an LED grow. I also like to stay closer to 350 to 400 umols during veg. Looks like you are pushing the plants too hard for the environment you've created for them. Get your Temps and rH up and give them a little less light and i think you'll see a marked improvement.

I like to water daily with a watering can and let the water go all over the leaves and floor if it's a bit warm and dry, the plants seem to love the humidity and water on the leaves at that age! I think you're on the right track lifting the pots so you don't over water
When top watering I don't drench but a bit of water in the soil evaporates nicely

Here's a handy interactive vpd chart. Use it as a guide to get your environment in check.

as soon as I saw those plants I thought of RH%.

yes they are struggling lack of rh

I had 2 of those temp/humidity gauges and chucked them in the rubbish, they weren't even close to each other!

Think its just the stress of it all new light heat shot up repotted
They seem to be looking a bit better
Gonna give the another watering hopefully that will be them kicking in
Humidity was always abit low under the hps light couldnt see that being the problem

Still looks abit grim like

I think they are looking abit better what yous think?

Carbon filter up
And rope rachets figured out
I use to just tie them things
They are handy as
