Late Outdoor Amnesia XXL Auto

Hello guys, I'm going to try to do a late session this year by starting right now. I live under Mediterranean climate so it should go alright. I got some sweet Amnesia Auto XXL from Dinafem and I put them in small pot 2 days ago in front of a window (cause it can get pretty hot here and I don't want to harm them) and they already got out ! I only gave them rain water and the ph was 6.5. I will start with very mild dose of Root and superVit to not burn them next watering and once they get the second set of leaves, I will put them in their final 18 l container outside. It's the first time I try to feed autos in a outdoor setting and it's impossible to find a comprehensive feeding schedule for them. If you guys have any tips I will be more than happy, knowing that I have the full Hesi soil nutriment line. Thanks for checking and hope to reply to you soon !
