Add more soil around stalk to support it. If you have a mix like FFOF , top dress and water in at 6.5.
It will allow plant to feed AND acclimate to it. Those affected leaves are early sets ( so they will become useless on their own time ).
She's moving forward , so that’s a plus. Autos are Always overthought , give them basic needs and let them do their thing. A complete “ bagged “ soil is enough to run an auto “ full term “ with staged top feeding throughout grow.
I posted a thread on this ( check sig ) .
Good luck.
