What light schedule are u running? I did a run with autos an left on 18hours start to fin.
I wish i had changed to 12 hours afta 4 weeks or so and i also restricted stretch by having my light as close as possible, but again, wish i had encourage a bit stretch.
U cud try reducing your on hours and see if growth speeds up.
I dnt really have any other ideas for u. Agree with whoever sed take ur time and dnt over love.
And remember the atmospheres conditions are just as important as feeds and waters and wat not.
Good luck pal!
