‘22 Summer Grow @D

light is a major factor to yield, but so is genetics. not everything grows donky dick colas, no matter how sophisticated you are at gowing it. more is fine until it is too much... a plant has a maximum number of photons it can handle per day relative to atmospheric CO2 and temps etc.. (best measured as DLI - daily light integral) so, depends on how bright that sun is... how efficient your LEDs are... you are probably fine. the attenuation from window and fewer hours is unlikely to be "too much" in any normal context. if plant ever looks super tired last 2-3 hours (extended period at end of day) or if it stunts, then you know it's probably too much.. resulting internode length can be a guide too

It is likely a pheno type, but could be other factors as well. Soil ph might not be as favorable for one as other, or it might be handling the limited light they are getting differently. You will need stronger light for decent flowering if you want them to produce. Your current set up likely won't produce much bud. You still have some time. Good luck 👍

High DojaMon, When you grow plants from seeds they always have 1 father plant and 1 mother plant. It depends on howmuch genetics did the seed take from the father plant and howmuch genetics did the seed take from the mother plant. It is not different with children... Brothers will not grow exactly the same height just because they are brothers. If you want genetics to be identically you need clones from a mother plant. Happy Growing! 😋
