Looking much better!
One thing I do regarding the water level that is a little different than most is:
I keep my water level one notch above net pot bottom from beginning to end. By doing this I do not have to top feed water. It's a personal preference, that saves time, p'Hing, etc.... .
I have also started doing the following:
Once the plant has a 5-6" root in the water, I add a small amount of Sucanat to the water. Sucanat is a natural, granular pure sugar that will encourage rapid root development. I started using it a couple cycles ago and can not believe how effective it is. I bought p'H down Sucanat (soaked in citric acid) and use it in mid-to-late seedling until week 6 of veg. It saved me a lot of $ on carbs and pH Down.
