AsNoriuanswered grow question 3 years ago She needs food asap, I hope you keep pH intackt for hydro too ?
You had to make mind what nute line you will use and she should be used already !!! Every company has nute use schedule, start with half recommended , if girls uptakes well, you can try to catch manufactory rythm, but your girl is like week behind for hydro ... So use schedule one week earlier than you are !!!
Plus don't forget, autos need less nutes generally !
All the Best !!!
