question about growing various strains and flowering times in same grow

I had a dream that I was growing 5 plants, all different strains. I was hand watering the plants in rock wool during the veg stage then using an eb and flow system for flowering with all plants in same try. What I didn't think about was the varying flowering times and how that would relate to feeding schedule and also the preharvest flush. In my dream I was using house and garden brand nutrients (aqua flakes A and B, multizen, drip clean, bud xl, top booster, shooting powder, and humbolts bush master). The strains I was growing were:

DNA Genetics 60 day wonder. Flowering time: 60 days from seed to finish.
Big Buddha seeds Chiesel. Flowering time:10 weeks.
Nirvana seeds Wonder Woman. Flowering time:8 weeks.
Barney's Farm L S D. Flowering time:8 weeks.
Green House Super Lemon Haze. Flowering time:10 weeks.

I had a feeding schedule for the nutrients and it had options of a 6,8,10, or 12 week schedule. In my dream the plants were still all in the planted seed stage. What would be the best way to feed these nutrients since some of the plants have different flowering times? What would be my best option for trying to flush the plants preharvest as well? I hope to hear back from some people and thank you in advance. All useful information will be greatly appreciated.

why waist time and talk about a dream grow. when your actully growing i will be more then glad to help. peace

use 5 different buckets with bubbler's in them and then you can put each bucket on a little stand so that they are all close to the light no matter how fast or slow they stretch
