3rd week of flowering and it seems to be growing slow now,

How long does it usually take for a Bubblelicious from Nirvana to fully flower? We are on our 3rd week and lately I havent really seen a difference in the Buds getting bigger. I am running 1- 150 w HPS, 15-18 inches away from the plant, 3- 26 watt soft white, each are equivalent to 100 watt light all running at 715 lumens. Also have 2 natural daylights that are 26 watts and each are equivalent to 100 watt bulb. I used Country potting soil that consist of compost, worm castings, sand and peralite and we also added some peat moss and a little bit of Vermiculite. As far as fertalizers I have used Earth Juice for vegatation and for flowering it's first feed was 3 days ago using Nirvana so I guess what I am asking is how long does it usually take for buds to fully flower? If any body has an answer I would be greatful and also if any body knows if the buds take a while to notice them get fatter and bigger? Thank you for your help.

vegitative growth slows after a few weeks into flowering as it diverts energy into flower production...there is usually a push of vegitative growth when you switch to 12/12 for a few weeks then it stops reaching up and goes full bore making bud. Get that 150watt HPS as close as you can without burning...When I used mine It was enclosed in an outdoor floodlight enclosure and covered by glass so I was able to get it about 3-4" away from the plants without burning them. I eventually took the glass off due to the low temperatures I am having to increase the amount of heat down towards the plant and I was still able to keep it about 6" away.

Scooby give your buds another couple of weeks and you see a big difference in their size.

They look right on schedule for 3 wks into bloom. As mentioned above things move frustratingly slow those first few weeks. And sometimes a week or more will go by when they're into bloom further where nothing much seems to be happening fast enough. More often it's only in the last few weeks or less somtimes rhat they begin to look like you'd expect. And it's only those final days that reveal the full potential size, weight and potency you want to see.

Forgot to answer your question better. 3 wks in means you've got another 6-7 weeks to go for the Bubble buds to finish.
