FIRST TIME GROWER

So I have never grown before. my plant is about 4 inches right now and I am completely lost on how to do much else. I have lights a set up all from people that have grown. I also have a whole bunch of different kinds of fertilizer. I don't know what to use. I have armor si 0/0/4, soul synthetics bloom/infinity/big swell, Humboldt countys own purple max snow storm 0/0/3 ; crystal burst 0/15/15, floranova bloom 4/8/7. please help me.

First of all, read.
The letters NPK. Those are important. Calmag. Also important. Grow vs bloom nutrients...important. Si is silica which is not so important.
You want a good base nutrient and a calmag supplement.
Snow storm, crystal burst, and the likes youll want to save until the bloom phase.
Get a good light, an a/c, A PPM METER, and a carbon filter and read. Good luck.

I think the kiss method should be implemented in this case. Find a basic 2 part or 3 part grow mix and just follow it's instructions until you become more familiar with growing.. youtube bud! Research, research, research! (Keep it simple stupid).
My first grow, I used "Advanced Nutrients, pH perfect", micro, grow, bloom.
