3 part question, any help?!

Ok so im close to chopping my plants, the 3 things i was just curious to know is:

1. When i flush with just plain water, can you feed the soil trays from the bottoms or is it better to water from the top so water and run thru the pot?

2. Will it make much difference if i cut a few days earlier then i wanted to (the trichs are more cloudy then amber)?

3. Is it better to dry then trim, or trim then dry?! (im hoping to dry within 4/5 days in the right enviroment)

Whats everyone got on the subject?

Im growing 9 bubbleberry under a 600w hps in 1.5 gal pots from clone. Vegged for 2 weeks, flowered for 7 1/2 once ive cut. What sorta yeild could i expect ya reckon?! Im hoping for at least 1oz per plant.

I grow in hydro, can't help with the soil question, so on to 2. Yes it will make a difference, but not a lot, weeks will take an uplifting sativa and make it put you on the couch but a few days won't affect too much.
3 I know there is gonna be arguments but i ALWAYS trim then dry, much easier and dries out faster. Trimming a dried out bud is hell to say the least.
As far as yield goes, your on your own with guesses, no pics no guess. One person could do twice as much as another, but just a few over hott days and errors can make the best of the best yield like an amateur (although they probably wouldnt have had the errors or over heating)

Thanks for the reply dude! Yeah i was thinking the same thing about trimming it before drying to speed up the process. Sorry about the pics thing but i aint got a camera at the moment, from what i can guess i think an oz per plant would be about right...i hope! lol Just cant wait to chop these baby's down and see what ive produced!
