Help my plants are close to harvest but i dont know when to cut them..?

Definately not ready. From what I can see, a month. Need better, closer pics, and a really tight close-up of the bud (macro).

It won't be ready until after the pistils have turned colour and shrunk, the buds have fattened up by 30 - 50%, and the growth on top of the buds has swollen.

Best way to tell, get a magnifier and check the condition of the trichs....clear = immature, cloudy = ripe, amber = past peak.
You'll want a mix, a few clear, mostly cloudy, and 5 to 20% amber.

Hope that helps.

what kind of seeds you use they look like sativa looks like you still have a bit to go you need a 30x microscope there only like $10 when the tricomes are mostly cloudy to amber some like to wait till their mostly amber for a heavier smoke but lower thc higher cbd
all depends on what your growing some sativa plants take over 16 weeks of 12/12 light to reach maturaty but their are indicas that can finish in 7 weeks your best off ordering seeds so you know the quality and flower times the only way is to look at it under a microscope espeacally if you don't know the strain

you have a while....at least 3 plus weeks

Definetely sativa-dominant plants. Pistils look to be still all white so you got a couple weeks to go.
Note the droopy close trim leaves in the later pix. That's usually a sign of over- or under-watering.
I'll bet it is under-watering. Now is a good time to flush all your plants, a couple weeks before harvest.

It looks like you've got quite a ways left. If you are 8 weeks (2 months) into bloom and they are only that big you must have sativas. Those leaves definitely look like sativa leaves. Sativas can take much longer than 8 weeks to finish... up to 12-16 weeks. BTW, you should start keeping time at when you send them into bloom, not at when they sprout (unless you're doing autoflower plants)... meaning, the numbers "15 wks" and "17wks" don't really mean much. A better way to describe them is 8 wks and 6 wks.

I think its a hybrid. Its called Hawaiian Grinspoon, gottem off a dude that worked in Barney's Coffeeshop (Amsterdam). The father's Hawaiian Haze and the mother's Dr. Grinspoon. He never mentioned the flowering time so thats why i'm in this position!

yeah it's looking like 3+ weeks longer

Grinspoon can take at least 18 weeks of flowering, if it is a grinspoon dominant pheno the buds don't really grow too much, you just get calyxes growing on the stems, not big flowers. That being said it is a super sativa high and some of the dearest weed they sell in Amsterdam (although price doesn't always mean it is the best).

To be honest you could have anything from 4-8 weeks of flowering left depending on phenotype.

Good luck, DST

and don't cut it early, or you will just get wed that gives you a high for a few seconds then a sore head.... and for a starter grower I would recommend checking out some easier to grow strains.
