Run out

I am coming to the end of the 4th week flowering and have just used the last of my nutrients, I have been using Dutch Pro. I am using fabric pots with soil. I have some Tomato nutrients and I know that people have had quite good results using it. I also compost and have good mature compost at the end of the garden. I can't afford to buy new nutrients for a couple of weeks. My question is.
Would the (tomorite) tomato nutrients be ok for the last couple of weeks. And would making a compost tea this late be beneficial?
Any thoughts?

I don’t have any experience with Tomorite, but I use TomatoTone without issues all the time. It’s certainly better than not feeding if/when needed.
