Hello. I'm not expert by all means but from my past 10 or so auto plants I've already grew i can give you some tips. Firstly I don't feed my plants at all for first 3-4 weeks, they just don't need it. Secondly its great you plant them straight in big pots, how I water young plants is half by "logic" and half of it is eyeballed. For 3 weeks just look at your seedling and imagine what you see over the soil surface, you roughly have twice as much roots underneath. That's why for first 7 days i water my plant twice a day with around 100ml water each time. From second week she's getting around 250-300ml once a day. In third week she's getting 500-750ml per watering and from 30th day i just add as much water to make my medium wet (in my case its 1500-2000ml every 24-36h)
Im 10 days behind you on my seedstockers white widow. I'm looking forward comparing how our plants will compete =)
