Soil, Water pH, Nutrients used and at what stage (veg, flower) how much and how often and the strength used, lighting!!! Since I grow indoors (I use a small bedroom, t8 lighting, 6400k for veg at 8 weeks at 16/8, then flip to flower (1 week) using 2700k at 12/12 schedule. Indica flower range is 8 to 12 weeks Maximum (I pick between 8 - 10 weeks). Sativa range is 8 - 16 weeks (note: North American 8 to 14 weeks (I pick at 10-12 weeks, Land Race Sativa takes 16 weeks to mature to pick) And most important is total darkness when in 12/12 schedule! Molasses also has been used to help "sugar" up plants. I can grow 6 plants all exactly the same way and they will not come out the same, all are different. I don't grow with a tent so I cannot comment on what or how your grows are not coming out, all I can mention is temperature, lights, humidity and air circulation.
