i have 6 plants that have been vegging for 4 weeks and ???

i have 6 plants that have been vegging for 4 weeks and have put into flower for 2 weeks, but not a lot is going on at the moment, at closer inspection they have 2-3 white hairs popping out between their legs and on the top of plants.
I feed them on Canna Coco A & B from being seedlings with no probs. I wonder if i need to change my feed when flowering.
If i need to change my feed medium which one is recomended. Thanks

you want to cut back on the nitrogen in flower, Nitrogen promotes green growth.

Id be patient, what kind of lights are they under?

600w dual spectrum lamp

I have one 2ft T5 Lightwave unit with 4 red flouresent tubes will this help to bring on the flowering along with my 600w dual spectrum light. Thanks
