Am I the only one?
Man I haven't been growing very long got 5 grows down but I've come to notice (could be genetics) but these autos don't have them terps compared to photoperiod, don't get me wrong I'm really starting to like the speed of autos just the past few haven't had them killer terps

When is the vegetative stage?
This is my second grow ever. I plan to let these grow indoors until 4/20 and then transfer to bigger pots outdoors. When can I consider these plants to hit the vegetative stage? I have heard when they hit their first set of 7-point leaves but that seems long. Is that accurate?

New white pistils close to harvesting
Hello, I have new pistils that appeared a few days ago only on the top buds. I planned on harvesting in 7 to 10 days max May look like foxtailing or not... Temps is 23°C so may not be heat stress. PPFD is about 600 so may not be light stress either Is it normal? What could it be?

Weird shit
I've nowhere else to ask this question.I bought hash that is insanely black and crumbles into nothingness at room temperature. When heating it instantly liquifies and burns for a while with no residue. It has almost no smell. Could it be some fake/designer stuff?
