is there something wrong with my plant?

ok so this is one of my 5 plants i have growing outside this year. The strain is unknown, used fox farms soil, was using tiger bloom nutes every other watering and watering every other day (recently stopped using nutes), i leave my water out for at least 24 hrs before watering to allow chemicals to evaporate, gets a least 10 hrs of direct sunlight a day, temps anywhere from 70-90 in the day and 55-65 in the night, growing it in cali.

So why the curling droopy leaves? i was thinking over/under watering (but i water when the soil is dry which is every other day or sometimes 2 days) or getting too cold in the night?

also whats your thought on yeild? its 4'3" tall and 2' wide, just started to flower about a week ago...started to see a few extra hairs a couple days ago

anybody?....i was thinking a ph problem but it cant be the soil or water cause it fox farms and i let the water sit out but i havent tested either of them

looks like too much watering to me

i only water by filling a propel bottle 3-4 times on it every other day or 2 days and i do the same for some smaller ones that are doing great

it does look very sad..perhaps looking in the marijuana problems section would be more helpful to get a diagnosis.
