Is 600 watt hps too little light for 3 plants???

Hey every I'm using a 600 watt hps with 3 plants I'm on week 6 but my buds aren't to fat is 3 plants too much for 600 watt ??

1 plants or 100 plants, it comes down to the space your covering more than anything.
Technically you could grow one plant to cover a 2x2 meter space or one plant could be 6inch wide.

600w should cover a 4x4 foot area, but if plants are really bushy you might not get much penetration to lower bud sites.

Its also strain dependent, at 6 weeks some strains are only half way through flowering and others are a few weeks from finishing. Some strains pack weight on late and some earlier. That's not taking into account any problems or stresses which would slow them down either.

Plus it depends on when your counting the flowering time from. If your counting from flipping the light schedule then you could be 1-2 weeks off on timing. Since they are transitioning and stretching.

Take a pic and post it.

Damn man thanks for the info here are some pikz to make it easier on u tell me what u think I'm closing in on 6 weeks on wensday the longer one is afgooey and the bushy one is bc diesel

I would say 3x5 area, the number of plants don't matter, other than vegging fewer plants longer for size.

Yea I've been counting from the day I flipped the lights

I think they look good.. I'm flowering 3 plants with a 2 month veg under one 600w and it's getting the job done. I'm running a cool tube though so I try to keep them in a 3'x3' area.
I turn my pots a half turn daily and rotate them once per week. I'm right at about 5 1/2 weeks from flipping to 12/12.

Nice yea I do the same rotate em every little while we are at the same time I'm 5 1/2 weeks since the day I change too 12/12 but I no that there's like a 10-14 day delay so it might take a bit more

Pretty tall plants for a 600w so that may play a part in it. Plus they look a bit stretched so each branch isn't going to be one long bud. But the plus side is every part is getting light to it so no shading of the smaller buds going on.
They look a bit high in nitrogen which may mean smaller buds, the darkness could be strain related though, I havnt grown those strains. Not so heavy on N that they are toxic or anything though. Tiny bit of nutrient burn.
If your 6 week from flip then your probably 5 weeks along or maybe less. I wouldn't worry, they will get bigger and will defo pack some weight on over the next 3-4 weeks.
All in all looking nice dude. All those buds will add up to a nice crop. Just be careful not to chop them early. Its easy to think they are ready when they are nearly there.

Top work grower.

For sure thank you so much for the help and feedback yea I'll be sure not to cut early lol Ima cut down on the N now which I'm guessing it's in the vegging food ?

I vegged for 6 weeks till I flipped the afgooey just blew up in flower

I'm really hoping they swell up some more !! I'm so anxious lol

I would say that 200 watts per plant is outstanding.
