First time with autoflowers

No nutrients started yet, water at 6.5 pH. Do Si Dos still smaller than other two but looks ok. This weekend will perform LST by bending the top over. I also have two Candy Cain Auto that I started at the same time that are about the same size and development as the others but they are in 5 gallon pots. I am testing over all growth between the 3 and 5 gallon grow conditions. The 5 gallon cloth with the auto water bases are keeping the bottom of the soil damp so far so they take a bit less water. When i am sure the roots are down to the bottom i will fill the reservoirs.
