Which nutrient would you suggest out of the 3 I ha...

I've enjoyed and had success with fox farm personally. Advanced has too many different bottles for me to keep up with. FF does have a good variety too but A.N just has so many possibilities. I can't speak for cyco. The one major positive i found with FF was that even though my tap water ran and runs a bit high ph wise, 7.5-8.2 if i added in the correct amount of the trio products my plants managed to receive a good phd water without being adjusted. I'm not the biggest fan of doing ph so that was a huge bonus and relief. Happy choosing. The plants look great so far. ✌️

Advanced Nutrients tried and true. I guess its really a matter of preference my friend. You can keep things really simple or go mad scientist on us. AN has a lot of great products and they move such a large volume that your practically guaranteed to get fresh nutes not some stuff that has been sitting on the shelf in some warehouse for the past year. I personally like Sensi grow with Voodoo juice and B-52 to start off with on grows. Then Sensi bloom Big bud and Overdrive during bloom. Also keep some cal/mag on hand at some point you will need to give her some. You can go to their website a print out a custom feed chart based on your base nutrients and length of veg/bloom weeks. Seems like everyone evolves with their nutes trying different things or blend of different brands to their current line up. Good luck hope this helps you decide.

hi there mate I have personally only used cyco products out of the three you have mentioned However I found them to be excellent quality with great results and easy to use hope I could be a help to you 👊
