lol this thread is too funny, it just rambles along doing its thing....

go ahead and molasses-ize any time, even in veg it doesn't hurt, =CARBON SOURCE= plant mass. Look up the term 'brix' if yer bored; it's a measure of sugar content in a plant and an indicator of health. I give my vegging plants molasses maybe once or twice during the veg cycle for shits n giggles and because i get molasses so cheap at the 'used food' [crash n dent] store.

Flsuhing is more like rinsing than watering. I mean, you pour water into the pot, but not for the benefit of the plant as much as to condition the soil- well durr that benefits the plant of course but you know- there's a Zandor sticky on flushing somewhere around here but the basic things to remember when flushing are:
-use about 3 gallons water for each gallon of dirt, pour it through slowly so you don't splash dirt all over
-water should be at room temperature about, and with a pH that is correct. Now, I'm growing in buffered compost so I don't check my pH, also because I know my tap water is STABLE at 7 and my soil is lower.
-after flushing, water with your fertilizer at ~1/4-1/2 strength to re-condition the dirt

Tahts it, it's simple. Now that's also why you should use a lot of soil lightener, because it makes flushing easier and less stressful to the plant.
