Help! - stunted plant

just want to say again this is 100% a response to low humidity, there is no problem unless the plant somehow takes a turn before growing out of the seedling stage

at that point depending on the pheno's resistance to low rh it will grow perfectly healthy but extremely slow

What should be the rh?

She looks kinda leggy. What light and how far?

Also as dank said low RH can cause seedlings to grow slower. That’s one thing which can change a lot from summer to winter months.

Now I put the humidity around %80. The distance between plant and light is around 85 cm. The light works %55 of power.

Dude. I have can hang a 600w MH the same distance. You can either lower the light or up the power. Do one at a time not both so you know where the limit is.

It's not stunted. It's growing roots in the huge container. Totally normal.
Should I only close the light on 6 hours of darkness period? It’s 19.2 C when the lights are off. My question is should I keep ventilation, fan and others working when the lights off?

Thank you guys!

What are temperatures with lights on? Yes keep air moving and exchanging 24/7.

When they are young you don’t have to worry so much about humidity as they aren’t big plants transpiring. This is when I lower or even turn the fan off so I can build heat within the tent. Although I do extract out the room via the tent.

21c is a good night temp. There’s a big jump in growth between 19 and 21 believe it or not
