I49 Zkittlez Feminized

Size varies a lot based on Strain, Light, soil and water. Mostly Strain. I have had some plants start off growing like crazy and others just take their sweet time. I do know that once the roots hit the bottom of your container/pot it will start to shoot up quickly. We start our seeds and little clones off in just a small 1"x1" cube. Once the roots are showing they move into a 4" pot for about 2 weeks where they start growing up quickly before they get moved into 1 gal pots. Then 2 weeks later into their final 5 gal pots. I know some prefer not to have the stalled period that happens when you transplant, but I like big plants and always try to get them to at least 24" tall for indicas and 36" for sativas/hybrids, just my personal preference. Yours looks healthy, so just give it another couple of weeks.

Wow Ocean Forest and Happy Frog and other additives? OF runs a little hot all by itself, while HF is loamy and dense. Let us know if you have soil compaction by end of grow. -> Dolomite might help that out, even with perlite in it. As far as how long the soil lasts before you add liquid nutes, I'll give my scenario. I run FFOF and Light Warrior in a 3/1 solution, and I never feed until after at least 30 days. With HF instead, your micronutrients could last even longer. But if you dont like your how your vegetative plants look, before that, you could start the feedings at a 50% strength.
