Yeah, I watered 1L per plant most of the time before turning on the autopots. Don't worry I watered till runoff the entire time because I was thinking about the potential buildup. Thanks for coming in and reassuring me though because someone a few posts back told me that 250mL is the most I should be watering right now which I'm not completely sure on still.
I'm keeping an eye on them every day. If I feel as though they're not bottom feeding and the roots haven't reached then I'll take them out of the trays and continue top feeding until it's time.
