Please don’t take this the wrong way brother but I had the same dilemma from the beginning because most nutrient lines will tell you that you can’t cross their new trance with another company because they carefully calculated every nutrient and supplement and when mixing with other products you end up overfeeding or underfeeding of a specific nutrient which makes sense but complete bullshit. I replaced my Biobizz fish-mix with Roots organic Surge. Also Biobizz don’t have any sweeteners so I am using Zen Products Candy Man. I am also using Bloom booster by Roots organics Terp Tea Bloom Booster which helps with fattening up the buds, etc… You just have to know what you are adding or replacing not to overfeed your plants. After speaking with a few professionals who run grow warehouses they all confirmed that it’s complete bullshit that you CAN mix nutrients with other company’s nutrients, that’s just the marketing strategy that companies use and like I said before there is some truth to it but they use it to their advantage. I hope this helps and if you’re still not sure then talk to a professional grower instead of talking to nutrient company owner or regional manager because they will tell you that you shouldn’t change or add other products to their line.
Speaking from experience
but if someone doesn’t agree with me, that’s totally okay and I do recommend doing your own due diligence on that subject and you will see that I was actually right. 

I just read your message about pro nuts
