droopy leaves?

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

Anyone? Also the stems r kinda purple

it looks to me like it is underwatered. how much rain have you been getting this year? a big plant like that can drink quite a bit of water.

O really? I though overwatered but I live in California so we don't get rain in the summer but iv been watering 1/3 gallon of water every other day or every 2 days

possibly root rot???

i think overwatering.

Do they perkup after you water them??
If so you need to give them more.
In flower they do use up alot of water...

um i was only watering with 1/3 gallon every other day so i did over 2 gallons and they didnt seem to perk up but i will check back tomorrow

also just found out the water i have been watering with has a ph of 8.5....no idea it was that high so i will start adj that for next watering

They should had perked up in 1/2 hr. after watering.
It must be the PH get it down to 6.5 or so.

I agree to lower your PH, but sounds to me like you are way underwatering. Since your plants are in the ground it would be tough to overwater. A third of a gallon is probably not getting down to the roots. My two cents would be a gallon plus a day cuz they are in the ground.

yep they didnt perk up so i got a PH adj. kit and keeping the waterings with nutes and without at 6.5....much better than before which was alternating between 8.5 and 5.0 going plain water to water with nutes
