Run into a problem

Here’s it goes so my plant is growing in some pro mix and ewc she is now been on 12-12 since September 2nd I ordered some dr earth flower girl and just got a email saying it is on back order it was supposed to arrive tomorrow I when she was in veg I used happy frog 7-4-5 I bought the fox farm trio as well bc I planned on using that but I didn’t know what I was doing and I had already used the happy frog so I could not use the grow big now my question is can I start using the trio now at least the tiger bloom and big bloom what should I do?

Also I used the happy frog on august the 8th when I transplanted her I then transplanted her on again on august 17th and I did not put any of the happy frog fertilizer I only used the pro mix and ewc so could I introduce some of the bloom nutes now in a small dose

Continue the Happy Frog .... until you get flower girl. Which surprisedly is available at local nurseries and Home Depot.

I checked Home Depot they do not have it yet

What do y’all recommend besides flower girl
