First grow help

Hi just curious as to when I should harvest. I put her into flowering around christmas. I have a magnifier coming so Ill be able to use that when it gets here but, can you tell as to what kind of plant it is? sativa,indica? maybe even the type of strain it is?? also the leaves are purple i think because it gets cold where i have it at night... i try to keep a heater on but cant all the time. Thanks.

Looks to be a sativa...which also instead of average of 7-9 weeks flowering goes to like 11-13 i believe or something close to that !! but looks pretty damn good bro
And also i got a magnifier glass but you can tell when a plant is done....the bud gets a tint to it looks like something you would buy damn near lol you will know when the time is ready when most of your hairs are orange and trichs show 1st sign of amber

and depending how cold its ok

Looking good man.. i also think it's a sativa dom strain nd depending on which strain could flower for a longer time. Just e patient nd dnt jump the gun too quick lol. Like whipp said u will knw when she's done.

Where are the buds??? It's flowering so slow your gonna be harvesting in July.
