you want more cool white light and less warm. you really dont need the warm IMO, some people would disagree. but for veg/seedling stage lights around 6500K are best.

try to get the temps below 80 F as lower temps will promote females (As well the plant just grows better).

it is more important imo not to risk letting them dry out, than risk over watering.

i water seedlings twice a day (but a very small amount, only were their roots are) they can dry up and die super easily. more so with high temps

and keep them on 24/0
