CFL and auto's

Im growing some auto flowering plants with CFL's but i need to know if i should switch light spectrum they are about 2 weeks old no signs of bud yet, i have them on my blue 6400k cfl light, need to know whether to switch to the red 2700k lumens or is it to early??

im in the same boat (day 10) but from what i read u should switch when u start to see flowers

Wait until you see that the plant has started to flower then switch.

alright cool thanks
