This is Greenhouse seed indica mix, but I guess there is some phenos or something. Strains: white rhino, lemon skunk, cheese, church, great white shark, el nino. These buds are church, and they are brown from like week ~3, that strange, you think i really should cut it after a week? :O arent churches flowering like ~8-9 weeks? How much could i get from these plants? Because this is my first grow
Ok, could be a pheno thing, hybrids can go either way.
You should look at the trichomes (the stuff that sparkle) with a magnifier. They should be milky, not clear and some should be amber when you cut. Some cut as soon as the amber starts showing, some wait until almost every trich is amber, it's a matter of taste. But they are ripe (contain THC) from milky and on.
Has it been 5 weeks since you changed to 12/12 or since they started budding? If it's since they started budding it wouldn't be that strange if they are ready in a week or so, if it's since you changed lights it's more unlikely but not unheard of. But like you say, some plants turn brown fast, i've had a plant or two that looked ripe very early on but needed a loooong time to finish. Trichomes are the only way to tell really.
I like the look of 2 0r 3 0f the indica dominant plants to the far right of this photo,
The top heavy darker green plant might not look as heavy yielding but that top should make up for it sorta thing, im more a indica/skunk fan myself and why these caught my eye i suppose,that and ive worked with fast varietys for some time now,40-45 days i find a normal flowering time for these, some not so good for breeding though, can be tricky subjects yes"
your unsure of its genitics? - big wide fan's thats for sure'
