It's been almost 2 weeks since they sprouted.

Your humidity is too low for those temps. Either add a humidifier, or rig up a bucket and wet towel.

I use this chart as a reference.

How much are you feeding them twice a day m8?? They haven't had enough liquid from the start for me and look dry as a bone in your pics, no offence.. what size pot is that?

 

[hope2grow]

The temp sticks between 80–86 degrees. Humidity sticks between 39-44. I'm using a Mars Hydro light.

Humidity is way lower than u want but that's not the reason they're slow/small in my opinion.. not helping but not the big issue.

I've been growing in soil for 10 years m8.. here's a link to my thread where im waiting on 38 seedlings popping at the minute.. if u want to jook in over the next couple weeks I'll show u how to get a seedling moving along in soil.

What nutes are you using? Are you adjusting your ph before it goes in?

Heres my last grow at 2 weeks old.. the pots are only 3L but you can see the size and development of the plants..

By 14 days old you'd like to see 2 or 3 sets of nodes/branches starting to form.

Roots will only grow when they stretch for nutrition. Always water at least the leaf distance away from the stem. Remember over watering is the biggest reason for failures.
Dunno why someone doesn't mention some type of moisture meter when they're cheap and an easy way to KNOW what's happening at the root ball...the most important part! After 20+ years, I still use one to double check ....ya gotta know some of these simple things....

Do you recommend a certain one? I like simple and “dummy proof” haha

These are 12 days old today and already scrunched a bit once from rookie overwater. Not much cuz I was only a little but I just learned here about not watering close to the stem. Oops! Another AFN lesson learned.

As dummy proof as it gets m8. I've used the older style 2 in 1 type.. light and moisture.. for a decade.. and it still does the job.. no idea about the light measure.. wouldn't say it's accurate.. but soil moisture.. spot on.. doesn't have to be fancy or expensive to do this job in my humble opinion.
