Hy herb, sure you can bro!
To make a long Story short u may just have a quick look at the Thread i started in the @fertilizer and soil section called "Plagron Royality"
https://www.autoflower.org/f26/plagron-royalty-mix-20824.html
Had a look, couldnt spot why you chose the LR f1 though!!
Don't think ive seen someone grow this strain before.
