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 8)
When top watering I don't drench but a bit of water in the soil evaporates nicely

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
