GOOD FERTS FOR SOIL??

Ok so i am getting ready to start my second indoor grow and have a couple questions about ferts. My first grow was done with MG and then i transplanted to reg soil with a 10-15-15 fert for flowering(don't know name brand off the top of my head) and i was not thrilled with the results. Maybe it was from transplanting?

Anyway i was wondering if you guys could give me some advice on a good 20-20-20 fert for veg and a good fert for flowering. Thanks in advance guys!

peace, anthony
