First tent grow - 80cm x 80cm x 180cm

Hazeykushhash Not looking good. After a full week above ground they are not growing much. I think I over watered the soil before planting. I read somewhere to soak the substrate before planting and subsequently read many different conflicting recommendations to only water gently after planting. I put about 10L of water into a 15L of fabric pots of Canna Coco plus. Also about 7L of water into an 8L plastic pot for green crack before planting. The other possibilities that have caused little to no growth is ..... Possibly too hot in the tent or too much humidity. Light was too far away at the start but since been moved to 50cm. No exhaust fan until now but I didn't think that would cause such damage so early No fans for approx the first week. Very disappointed so far and I feel it's game over already. If anyone has any advice I would greatly appreciate it. Thankfully I have one more green crack auto seed that I'm germinating separately to hopefully save my blushes and learn from my mistakes.
