From a fellow grower: My 3 remaining sprout seem to be growing very slowly. They were started first week in May and next week will be almost 4 weeks and the sprouts are barley one inch tall. I am only watering (misting) every 2-3 days and doing in early morning and early evening with just the top 1/2 of soil getting moist and completely dry in about an hour. This is an outdoor grow here in Phoenix Arizona. And I am also using the recommended soil (Happy Frog) amended with powdered worm casings and steer manure. Strain: Dos-si-Dos feminized.
Climate: Outdoors.
Temperatures: Day high 90’s to 100’s during the day, 70 degrees at night
Light schedule: outdoor light from 8am-2pm

A seedling only needs a couple ml of water each day.
The best method for seeing that a seedling has what it needs without risking root development problems is to instead use a dome and to not water the soil at all. Use a clear Solo cup or a cut pop bottle and spray inside of the dome a couple of times each day. The plant can get all of the water it needs via the leaves from the humidity in the dome. Start watering a few ml a day when the plant outgrows the dome.
4 weeks old, even though its 1in tall its not a seedling anymore. How big is the pot that they’re in. I think I would give them more water at this point. Take a solo cup put it over the plant then water around the cup then remove the cup, then wait 2-3 days before watering again. That will encourage the roots to spread out. At 4 weeks there could be a lot of root growth going on and not much happening up above. Especially if the seedling was put in a large pot or in the ground.
This is my solocup area little domes help them get going I found its easy to drown them. Hardly any water. And when established I go by weight on watering damecas big sisters.
Same applies to ILGM support, fill out support ticket. Lol. Some pictures would help also.
Add to this the typical LOW humidity and if you are in fabric pots the dirt could be bone dry throughout. I agree with watering it more than a mist or a few drops. In that arid heat you may need to water it twice a day. Ever considered growing inside?
Oops, outdoors, sorry
Your biggest problem right here…
I have spent a lot of time in Phoenix and add in the wind and its a brutal environment.
Its why rock gardens are so common.
The grower was not able to send pictures.
