wattage question

i am 2 days into bud they are under a 600w at the moment. would it be best if i turned the wattage up straight away to 1000w or should i leave it a week or so?

If you got it, use it. Assuming you can adjust your light to plant distance and cooling appropriately.

yes i have a total of 1600w would i get better results if i use it start to finish in bud or gradually build it up through the weeks?

I say the more wattage the better the grow, the more the buds.

Yeah figure out your sq ft of your grow space. The minimum you want is either 50 watts/sq ft or 5000 lumens per sq ft. I'd shoot for 70 watts a sq ft or 7000 lumens. That's just what I run at and get good results.

its 2m x 2m

you need the other light turned on if you want none airy meds!
