Time Released Soil

Hey guys I have some plants growing and after awhile I realized my soil is "Time Released Feeding" veg stage for 2 months. I want to flower before the two months is up but if I start feeding bloom food it will prob burn my plant right? Anyone with experience or knowledge with this please help me out.

Note. I grew the plants with dwc for 2 and a half weeks and then put them in soil b/c of past problems with dwc and me. They've been in soil now for only 2 weeks and are 8" tall already. I can't wait 6 more weeks to flower because of my grow space. Any ideas appreciated.
