Scared about feeding

[EyesOfTheWorld]

My first grow is starting to look like:

Outdoors in 7 gallon grow bags using a high quality soil like FoxFarm. Growing 4 different hybrid strains.

The nursery gsve me a FoxFarm feeding schedule, and now I’m depressed. Part 2, Part 3, what’s the difference? Where is Part 1? How many products do you need to buy to meet this schedule?

You need to speak to your retailer or see the manufacturers website to get your head around it

So there are basically two types of “grow” organic and hydroponic, yes?

I’m not doing hydroponic for various reasons, simplicity being the main one. So if I’m doing organic (dirt) I’m feeding the soil, and the soil feeds the plant. Is this also correct?

And if I use a new high quality soil (Fox Farm for example) I won’t need any “amendments” for the first few weeks, because the soil should be ready to go. And after that I should only need fertilizer for the veg and flowering phases?
