Purple Urkle Clones

A good week I think. Buds are starting to show up! One of plants has almost grown into light. They grew a lot in first and second week of flowering. Gnats are still visible but not near as bad as it was (which wasn't very bad) The powdery mildew problem has also not gotten any worse. I suppose this is because of my new watering schedule; once every three days. The top inch or two of soil is now drying out between watering. Also, the weather has taken a turn towards winter with cooler temps and lower ambient humidity. This means furnace running more which also lowers humidity in house and subsequently, the grow tent. I trimmed a ton yesterday. No idea what 'm doing but I did watch a video on the subject and the presenter was showing his technique of removing most of the big fan leaves with purple stems. I sort of did the same thing and the plant is much more open now with more light getting in center growth. It's also easier to water as the very bottom of plants are completely opened up. I'm thinking these are not Purple Urkle as Purple Urkle is an Indica strain. My understanding is that Indica grows out, remaining relatively short. These have grown mostly straight up and from the floor, are over 5 feet tall. Doesn't this make them Sativa?
