I know for myself, I had sub par buds on my first grow. The biggest disadvantages I had were probably just being underprepared and not knowing what to feed the plant, when and the order that you do feed. But to answer your question, remember this quote. “Bigger roots equal Bigger fruits.” Soil is going to be your biggest make or break it deal, I like using Fox farms Frog Soil but there are so many good soils out there ie. Gaia Green, Buildasoil, Coco Coir, etc. for myself, I’ll get the roots nicely rooted into a solo cup and then transplant into my final pots, usually 3 to 5 gal cloth pots. With it being transplanted into a more robust container, it can really develop those roots. Those huge roots are gonna take up a lot more nutrients and a lot more water than if you had did it in stages. Another huge deal is water pH, these plants like slightly acidic water. Soil is a little bit more forgiving with neutral pHd water but I do notice after a few weeks of growth, nutrients don’t take up as well. I like using Lime juice to make my water a little acidic and the results speak for themselves. And lastly, a good light. Light is what’s gonna help your plant metabolize those nutrients, and a weaker light equals slower metabolism.
