@Flexus13 Welcome to AFN
A good indoor grow starts with the environment. You must provide the basics and it is harder than it sounds. Cannabis is a weed and will grow under many conditions but if you want it thrive then you need to optimize these conditions. Night temperature 68°F Daytime Temperature 78°F, Relative Humidity >40% <60%, ~40 DLI (daylight integral) at the proper spectrum, gentle continuous fresh air movement. Good Quality starting water. Most indoor growers use a tent to help control this micro-climate. The taller the better.
Then decide on a grow style that suits the time schedule you are willing to devote to the grow. After preparing the soil (which can take months on DIY soil) Organic Living Soil take the least amount of tent time. Time demands go up from there on other styles.

Precharged soils have a learning curve as to when and how much to feed your plants. Many new growers mess this one up by feeding too much too soon. I work the Infirmary and this trips up many and is difficult to get back under control. Less is better.
Coco is a form of hydroponics and many growers are successful in coco but you need to do the research first.
Hydroponics is a full time every day, even multiple times a day grow style. A solid understanding of salt nutrition is helpful in this style. I grow Hydro in precision drip irrigated rock wool. A DWC Bubbleponics bucket can be done with a little research. Some of the biggest best plants I have grown were in Bubbleponics.
Choose a grow style then choose a nutrient line designed for that style of cannabis farming and use that entire line. Do not mix and match based on flashy names or bottles. Nutrient lines are developed with the products designed to work together to keep the all important "Balance" in the media. To understand balance research Liebig's Law of the Minimum.
Understanding your water's starting profile is important. If you are on municipal water you should be able to get a water quality report off the internet. The sections we are interested in are the Hardness and Sanitation sections.
Tag me with that information and I can help you understand it.
