Plant in flower?

I wouldn’t say the flower has started yet. When you see her show her sex then you know the flower has started. You know these little hairs coming out. In the beginning they are green but they turn white

is this an autoflower? if not you control when it flowers by giving it uninterrupted darkness - usually 12 hours to be safe. if that is an autoflower and it's 30days from sprout, i'd start to be concerned that the breeder accidentally sent a photoperiod seed or fucked up the autoflower creation process and you got inconsistent autoflower seed.

I don't think the flowering has started. There will be small white pistilles that will appear when the flowering starts, and there will be the stretch at the beginning of flowering as well, the branches will start to grow faster. 30 days is a bit early, it takes another week or two 😉
