Is it OK to finish Veging, under my 600w HPS....

So i started 3 plants from seed (2 Blackberry, 1 Blue Mystic), and was veging them under a 150w HPS, along with 3 30w CLFs..

I started them of in large Gatorade bottles, and theyre very healthy and about 5 inches tall each...

Yesterday my mother and i transplanted them to 2.5 gallon slush buckets, and put them back in they're grow closet. Now my question is, should i stick with the current amount of light im using right now, or do you think its ok to finish Veging them under my nice 600w HPS, which they will also be flowering under...

Ive found in the past that when i start a seed and keep it under the 600w for its entire life cycle, the vegitation grows so thick that the 600w isnt powerful enough to penetrate deep enough in the flower stage and i end up getting underdevolped buds....

any comments would help thankx...

i dont see why it would be bad

I would put them in there to finish. Not only are they going to receive a kick start with more light at the end of veg but they will transition nicely into flower and will be already used to the light intensity. Just set your 600w up a few feet and lower it slowly over the next few days. If your having a problem with light penetration perhaps you should adopt a scrog method.
