My indica strain is a y. Not a t. My sativa grew with 4 lights on the outskirts and nothing directly above and I pushed the branches down every day to grow more flat and widen up due to how my lights are.
My sativa just took some piictures. The non serrated leaves came off the bottom branches. And I have no fan leaf or growth there before I topped. After I topped 4 branches popped out. One on one side and three off the other side can see in picture 2 and 3. You can see its height in the last picture it has grown a few inches since last night.
