Outdoor vegging/Indoor Flowering

Hey whats up, I'm growing 5 different stains of purple weed. All clones from a medical marijuana dispensery. 3 of my clones are 4feet or taller, those were started from mid to late april. I've got one more smaller one that I started early last month. And I got one small granddaddy purple plant thats just starting out. I got the three big ones planted in 5 gallon buckets with drainage holes, and there are rocks at the bottom. I used a mixture of miricle grow potting soil, and bat guano to start them off with, and I've also ferilized with mirilce grow plant food, with it high in nitrogen, and I've also use a hydrophonic chemical nutrient to vegetate. Just recently I started moving the biggest of the the plants, which is a purple erkle/grape ape hybred, inside to a dark closet for 12 hrs. to force budding. Five days later, there are visible buds with white pistols sticking out everywhere, there are alot of buds. This made me very excited because I didn't know if this would work, and I heard you can shock your plant by moving it too much. Now that it's apperent the plant is going to live, I started using a hydrophonic blooming nute today. So my question to you intelegent people is: Whats can I do to maximize the flowering stage, an produce big beautiful, potent, purple buds.

Seems like you are doing everything you can. Just take care of it and feed it every other watering with a nice dose of flowering nutes. Only other thing you could really do is invest in a product that supplies your plants with the vital carbs and sugars they will need in flowering. Something like Advanced Nutrients Bud Candy, Carboload, or Humboldt Nutrient's Honey Organic ES would work great.
