@Kaillan,this is a robust grower. That said some strains couldn’t take the intensity of light at such a short distance as a young seedling. Keep an eye out for signs of light burn. Too far they stretch, too close them burn or slow down due to stress. Yours is looking fine.
How goes the battle?
Everthing looks great,try to lower your daytime temps a little if possible👇 to much heat is a major stress for your plants.
If you add C02 to your grow room this helps with stress . A little breeze on your plants helps them to become strong.
Hope this helps a little👊
Good luck👍
