Anybody had a hybrid pheno being full sativa?

I have a lemon og (or presidential kush to some) that is 60/40 indica dominant. I'm nearly 7 weeks into flower with nearly 100% white hairs sticking straight out. Trichomes arent fully developed with most being clear. Buds are putting on size every day but seems very airy (like the calyxes havent swelled much) but has started to fill out in the last week. Seems to me she could go 12 weeks!!?

Has anyone had a nearly pure sativa pheno from an indica dominant hybrid?

It happens.

What type of light and how many watts? Weak light will lengthen flowering time.

8 week flower is with the purest of indicas. Any sativa can lengthen flower time.

I've seen short flowering fat leaf plants and thin leaf flowering out of the same batch.

Thanks for the reply whitebb2727. 1 plant under a 600w hps, scrog. With co2. Temps are around 32 degrees Celsius (on the higher side, but am dosing 1250ppm of co2) i have a chemdawg and a Ww x bb both under a 600w each in same conditions, going great with rock hard buds. The other strange thing is it has alot of 3 leaved fan leaves. Almost like a monster cropped plant reverted back to veg. Have no light leaks at all.

The other thing i was considering was a possible mutation or bad seed?

I have heard of a 3 leaved og kush pheno. Very rare and sought after. But I doubt id be that lucky haha.
