Fert question

I have been using miricle grow 8-7-6 for the last week or 2 with no burns but i just got some expert gardener 10-15-10 for flowering but i was wondering, i see everyone here hates miricle grow so do you think i should just switch to 10-15-10 even though im still in veg? do you think it will grow better?

thanks

btw im growing outside
