Okay To Use?

Hey guys!
My plant has rebounded from the light stress from my new HLG 100v2 and is doing great. Potted up to a 4.5gal and she’s loving it. Growing in ffof.
I’m lookin to flower within the next few days and have never really done this before. My outdoor plant I just let do her thing.
Anyway I have this bottle of nutrients from a grow I failed a while back and never even opened.
Can I use these nutrients? I believe I got em at a hydro store like 3 years ago.
Will they be any good?
And when should I start using them?
Any advice is welcome thank y’all

The Nutes will be fine, as long as they weren't stored where they could freeze.
I'm more hydro and don't go to Bloom Nutes until stretch is about done.
Good Luck

For me, that stuff would be good for early bloom, but I like using a 1-2-1 ratio after the 2nd week of flowering. And I use that until the end of week 6, then I like using 0-2-2 to finish them out. But that's just what I use for growing pure Sativa or the heavy leaning Sativa plants I grow, and when I grow Indica leaning plants and or heavy leaning Indica hybrids, I use a 1-2-3 ratio after the 2nd week of flowering, And I use that until the end of week 6, then I like using 0-3-2 to finish them out. And I do that because that seems to work the best for me and my plants.

I’m growing wedding cake is it’s pretty indica heavy, if not %100.. will the 1-4-5 work or should I drop down like piratebug suggests to an 0-3-2?
What’s a good fert with this ratio man?thanks for the replies y’all

Pure Blend Pro is great stuff all the way through flowering. It's a complete fert.

Nothing wrong with those nutes except the price. Use them up if you have them.
