Auto indoor grow

I have been slightly bending and picking leaves off the original 3. The mazar that I had to start late has not been topped. I believe I am going to use this one for making my feminized seeds so I am trying to stress it the least amount possible. I am top feeding and have noticed a small amount of fungus gnats so i added a bit of diatomaceous earth to the top soil which seems to kill them instantaneously. Have not seen any since. Next week I will be putting together a DIY colloidal silver generator for the fem seeds.
