Fertilizer from flowering to finish

I have been using a 20-20-20 water soluble during the grow. I am growing in the ground. The plants have been great so far. But now they should turn to flower in the next 2-3 weeks so curious as a newbie what I should be switching to. Nitrogen isn’t needed much during flowering, right? So should I be stopping the 20-20-20 now and switching to les Nitrogen? I will post what I have to switch to and curios if it will be ok and/or how often should I be using it? I honestly don’t know this brand or if it’s any good. Thoughts?

Nothing wrong with that item, just not very cost effective. I would stick with the more economical dry ferts. I know Jack's Finish and Maxibloom come in sizes from 1kg-22kg to fit your needs.

I personally like the Jack's profile better tham the Maxibloom.

I know there’s a fertilizer that does like 5-30-20 for flowering reefertilizer but it’s powder based so idk if you don’t like that or if it’s the “perfect” choice but it’s for cannabis

Jacks classic blossom booster is 10-30-20. Cheap and easy

I’m going to start putting more N during flower, I always start to run out week 4-5, and I always forget before it’s too late.
