Autoflower nutrients preflowering stage

Hello everyone, just quick question about preflowering stage..I got some new fertilizer 13 : 40: 15
Would that be good enough?

It may be good, not sure.

If it were me and it hadn't finished stretching yet I'd still want to be giving it something more balanced with more nitrogen so it can handle all the growth. It varies with the strain and how big she stretches in flower. I use 4-4-4 until stretch is over then switch to bloom or a week of half grow half bloom first but I use dry fertilizer in organics also.
