Soil help needed!

Hello. Well, in the past I used Miracle Grow Organic Choice mixed with perlite 70/30 and fed with Expert Gardener products. All went well, but that stuff obviously sucks compared to something better so for my next grow I decided I'd upgrade my soil and nutrients, etc...

So I went to the hydroponics store, and bought good nutrients because this time, I'm not growing just any bagseed. I'll be growing Master Low and Powerstout. I decided I didn't want anything with nutes already in it, such as Miracle Grow organic, so I purchased a few bags of Hyponex potting soil, and plan on mixing it 70/30 with perlite, for drainage, etc...

I'm wondering, if that's a good enough soil mixture, or if I need to add anything else to it. I'll be feeding them the complete line of Technaflora foods. B.C Grow, B.C Boost, and B.C Bloom along with Thrive Alive b-1 red, and Thrive Alive b-1 green, and Awesome Blossoms in the final stages of flowering.

I also have bags of Miracle Grow Organic, that I can mix with perlite instead, if the Hyponex isn't good enough, but I'd prefer to have something that has no nutrients in it, so I can feed it with it's food, and not overfeed it, because the soil already has slow release nutrients, etc... That's why I felt Hyponex was the right choice.

Please reply soon, as I will have to transplant them in their jiffy pellets into pots soon.

Peace,
horror business :rasta:

A plain ol' boring unferted soil with 30% perlite will give you plenty of freedom to use liquid nutes.

The final repot before flowering, you could add some bat guano if you like.

Ok, thanks, that's what I was hoping. This is my first time using liquid nutrients, in the past, I've just used the basic plant foods that are a powder.

Since this is an unferted soil, does that mean that I will have to add nutrients sooner than I would have in the past? In the past, the miracle grow organics choice/perlite was good until about the 3rd week, at that point, I needed to add food, as it was developing a nitrogen deficiency.

Will I immediately need to add some nutrients? This would be so much easier if I had a waterfarm... which is on my wishlist, lol.

Also, it tells me, when using my nutrients in soil, to use them every third watering such as (feed, water, water, feed). Hyponex and perlite will let me do what I need to do right?

If your plants are big enough that they need a transplant (5 nodes), they are ready to fert.
Or you could watch for N def to set in, and let your plants tell you when they are hungry... but that's not optimal. Since you did this once before, you know that week 3 they are hungry, so start a 1/2 strength feed halfway through week 2 and watch for any sign of burn.
Feed-feed-feed-flush or something is a fine schedule... the flush step, if your plants are looking healthy, doesn't have to be a crazyu full flush, just plain water until it runs out the holes. I think all dirt growers do it differently, lol... your plants will tell you what they want. Listen to them.

The only problem is, before I had regular indica plants. This time, I'm doing powerstout and master low, so they really don't have a vegetative stage, so I'm wondering if I should feed them a small amount of b.c grow and b.c boost, before I switch to b.c bloom and b.c boost.

They do, don't fret. It just ends naturally for them rather than under 12/12 lighting.
I don't grow autos though. I'm not sure how different their nutritional requirements are, if at all.
