Main lining

Hi there, Plants at your age drink approximately 300ml per 24hour.But you don’t need to water everyday.As you are growing in 5 gallons pot, I think you don’t need to water for at least 10days .Make sure your top soil is dried for 2inches down and know your pot’s weight when to water and after watering.You don’t need to use nutrient everytime you water as your are growing in soil.Always check your water pH and ppm before watering.Make sure there’s 10~20% run off and check run off pH and ppm also.Happy Growing... ✌️

This looks like wear & tear, not bugs. It can happen when they are small and you're handling them.

Too early to tell. Both sexes have the same bracts (those little leaves you are seeing). You have to wait until the reproductive parts grow in the bracts. Two white hairs mean female, so keep an eye out for those.

Flowering stretch lasts a few weeks depending on the strain but it seems like your is about done and starting to focus in bud formation so there's nothing to worry about height wise. Amazing main-lining work!! Good luck and happy growing :)
