Hey man sorry to hear about the yellowing. Has your soil been able to dry out lately or has it been like soaked for a while?.. Cuz it could be root rot i hope not though man or either root bound but you just put them in those pots or am i wrong?... If the new growth stays green and keeps growing good and normal and only those leaves that are already yellow die and fall off you should be good thats normal. But if you think it may be root rot do not give them water again untill the soil has dried out a bit and try to not let them get rained on.
