Watering should only be done when the plant needs water. Heft the container when it is pretty dry to get a feel for what it would weigh when your baby is in need of watering. My plant is in a 2.5 gallon container and she needs water about every 3 days. Today is the third day, but the container still weighed too much, so she will get watered tomorrow. Better to underwater than to overwater. If you underwater, your plant may droop a bit and will then recover when she is watered. If you overwater, you will kill her. When watering, you should slowly pour the water over the entire surface of the soil until you see runoff in the tray under the plant. The reason I say pour slowly is so the water will mostly be absorbed by the soil and not be running so swiftly that it pours right through and into the holding tray.
Grow Big should be introduced a few weeks into the grow during the vegetation stage. Best indicator is by looking at your plant. If she is in need of nutrients, she will lose color. Of course, she will still be green, but the shade of green will get more and more pale if your soil nutrient level is not sufficient. Reciprocally, if she is getting darker and darker green, you may be overdoing the nutrients. A good, deep shade of green is desired.
As for Big Bloom and Tiger Bloom. I use the Big Bloom when moving to flowering stage and then switch to Tiger Bloom when she shows. This is what I do, but I would imagine that switching back and forth between Big Bloom and Tiger Bloom would be fine.
When using nutrients, be sure to go softly. Always start by using much less than what the manufacturer suggests and work your way up to a stronger mixture. Better to undernute than to overnute.
Now, for the sugar thing. I do use molasses. During the flowing stage, I use a teaspoon of molasses for every gallon of water and only use molasses every other watering.
Hope this helps.
