Here is what I know and take this to the bank. I am not A botanist like Big or some others on here. Everything I have learned I got from other people that I listen to. Most on pot sites aren't worth listening to and give bad advice. One must learn to listen to good advice and ignore bad....that is an art in itself. Over the years I have surrounded myself by the good advice. Based on trial and error and listening I am dialed into my style of growing.
Growing this plant is relatively easy.....perfecting a technique is hard and takes time an patience. Why I use the ingredients I use, why do I stop the cal/mag and other supplements 30 days out......because I listen and learn. Why do I dry/cure the way I do....same reason.
I by no means think I am the best master grower in the world.....NO I Am NOT. But I am a perfectionist and I take a lot of pride in my work. A job half done isn't worth doing.
If you mean the veg nutes, yes, I use soil, and it has nutes that usually get them through veg.
I believe pute uses both, grows in promix/sunshine 4, which has no nutes, so you must add them.
Good point Bubba. I use ProMix (can't find SunShine these days) because everything my plants get is from me not some premix soil done by others.
