Question about nutes

Ok so I transplanted my plant on august 5th. My soil is a mix of pro mix with some ewc and I used happy frog 7-4-5 for my fertilizer my question is when I transplant to a 5 gallon pot and flip my light to 12-12 can I use the liquid fox farm trio even though I used a granular fertilizer first I am so confused on what to do. I know when u start the flowering phase u want a fertilizer that’s not as high is nitrogen any input would be much appreciated happy growing riu

Let the plants tell you what they want...

If the plant looks hungry or like it needs to be fed, it's OK to use the liquid fertilizer to feed it.

Good Luck!
