Will this be alright?

Say I grew with ONLY warm white (1,200) lumen bulbs.

From seedling just one bulb, to veg 4-5 bulbs

to flower 6 bulbs. Think it will be alright?

For veg I would do 24/0 and 18/6 mixed

flower 12/12

2k lumen min per sq ft. If your plant is in a small enough pot it will produce flowers np. 10k lumen+ would be optimal.
