Planting for the first time, growing slowly, please help

[CN-man]

21 days now, why are they still like this, I can see that they are still growing but why are they so slow.
I use a 120W CFL tent temperature above 30 °C, very hot I know, but I don't know what to do, can only be blown with a fan, and the humidity is 60%, the air circulation is not very good
Last week I discovered that high salt in the coco soil caused a nutrient burning. So I rinsed my plants.
PH I have been watering between 6-7,
They are not dead, they don't show obvious problems, but they don't grow up. Why is that? WHY?
This is my first planting, I am going crazy.

They probably need a transplant

get the light closer, add a small fan to make them wiggle a little, and control your watering then transplant when u see them boom

if your having temperature problems your gonna have a hell of a time watering that coco coir..

and on top of this~~ your pots shouldnt be transparent.. try wrapping them with black plastic or something that will block light

Meant to add you don’t want transparent pots, roots shouldn’t be exposed to the light..

Add a second light. At least.

Medium & containers look like they dont have enough perlite & oxygen for the roots to thrive / grow

Temperature is a big factor too. Too hot and the plants will be so busy trying not to die. The hottest you want is 27c and even that is on the high end

A week has passed, the plant is already 28,
Thank you guys, I added enough perlite and created a better environment, adding a fan to let the air circulate. But my LED is not assembled. So I put him outdoors, under the sun. New problems have arisen. They seem to be both male and female.

That's okay. Growing, like life, is a learning process. You're that much closer to having a successful grow!

Get rid of the male unless you're trying to make seeds
