Plants growing slowly but looking pretty healty

[frankthirtyspears]

Hi guys, i'm having the doubt that my plants are growing strangely slow and i'd like to know where am i making mistakes or anything related so i'm going to describe the entire process up to this point to know if there is something particular i'm messing up. The strain is Green Gelato Auto from RQS, after they germinated in the paper towel (the two in the plastic pots 8 days ago and the one in the terracotta pot 7) i planted them. After this i kept them inside some kind of greenhouse room with a window open and made them take 5 hours a day of sunlight for a week (from 3 p.m to 8 p.m). Then since they were stretching a bit i removed some soil around them and lowered them so that they look pretty much as now, i also moved them outdoor in a balcony were they now receive direct sunlight from 10 a.m to 6:30 p.m. I give them 5-8 hits of water with the sprayer every 2/3 hours in order to keep the ground moist. The temperature is 20-27 degrees usually during the day and at night i keep them inside for the moment. I'd be really really grateful if someone could help me figuring this out, also feel free to ask if i didn't put some important informations. Thanks and have a fantastic day
