Question related to nutrients, please help

Hello there, I'm going to try my first Hydroponic growing next week with 4 plant and I can really use some suggestions about nutrients.

For drawing a clear picture, I bought Autopot for 4 plant, my mix is going to be 50% coco 50% Perlite, I have growing tent, LED lamp, HPS lamp and all the other necessities. What I'm having problem is nutrient part because I've never used coco-perlite mix, never used Hydroponic in the past and I'm somewhat beginner in general.

The nutrient I'm thinking buying right now is "General Hydroponics FloraNova Tripack", this kit has;
473 ml FloraNova Grow
473 ml FloraNova Bloom
0,5 Lt Ripen

I'm not sure if these will be enough for 4 plant and even if these are good am I going to need anything else on top of these. Any suggestion is welcome, please help this poor fellow out Thank you.

i'm not a coco grower, but in general for hydro all you need is floranova bloom. nothing else. except a bottle of cal/mag to have on hand if you need it.

I've done many grows with coco in a flo n gro system and I've had great results with advanced nutrients coco line. I use the sensi a+b coco and the big bud coco. Other than that I will add some silicate in the barrel and that doesn't necessarily need to be advanced brand silicate. In flower I will add in some Nirvana and some bud candy and I get great results. Typically get the same yeild each time unless there's environment issues. But in the years I've been growing I have learned that each grow is different and each grower and shop owner will tell you that one nutrient is better than another so it really will come down to experimenting with your grow and finding what's best for you.
