i am growing with a 150watt MH with a nuetral white bulb. its coloour temp is 4000k, will i run into any issues later on or is this ok to grow with?
 
Probably better for flowering than vegging, 4000K is a bit on the cool (red) side. But will do at a pinch.
 
Your plants will grow but they will grow slow. Better off using 5000-6500k if you can. It's closer to the spectrums of light the plants need from the sun for proper photosynthesis.

Take care,
