Ok so this is day 48 of my auto bomb grow from germinating day 45 under the lights, They seem small for the this length of time can someone point me in the right direction as to what's stopping there growth?

Using 3l pots
Canna coca for medium
Ph is 5.6-5.8
Nutes are canna a+b 12 ml of each to 5 literes of tap water
Lighting is of 18/6
X2 45w cfl (now using the 2700k flowering cfl's)
Watering between 2-3 days 200-300 ml each pot per time
I have canna bloom to add at a later stage

I have a 600w sun master I've been thinking of trying as I thought maybe the cfl's weren't powerfull enough?

Any advice is appreciated thanks
