Sweet Tooth - From Seed

So updates since my last post a couple weeks ago. I'm finally seeing female pre-flowers, the pistils spurting out are absolute evidence of that. I was starting to worry a little bit, but as my brother in law said, don't overthink it. Which I'm notorious for.. anyway. So the plants are doing great, as you can see in the images the purple plant is 11 inches taller than the white plant, this concerns me a little as I don't want to keep the light much higher than it is without risking stretching the smaller plant. Which doesn't sound horrible, but really what I want to see is the white plant catch up. Maybe that's a pipe dream, but time will tell. I have gradually increased the amount of watering I provide to the plants just to keep up to them. I spent a good hour last week trimming out all the under growth I felt was useless to the plant in it's current state, also I had an eye on making watering easier, I removed every shoot or leaf between the crown of the plant (dirt line) and 6". This will do for now but in the future I will need to trim more. I don't want to take too much from the base of the plant the because the plant is meant to be a mother and the lowest branches will provide the most ideal cuttings for clones in my case, as they have increased levels of the hormones required for rooting. The clones are doing great s well, they are now 6" tall and I will be starting a new diary for them next week. This diary is now complete as the main function of it was to monitor the growth of plants from seed to pre-flower mother plant capable of cloning from. Thank you for everyone's comments and help, it was great sharing this experience with you.
