Dry and wet....
Dry means to let the soil become semi dry, not totally dry.
Wet means when you water the plant.
By all means water the plant (do not keep it soggy tho, let it breath as HIE said). A general rule of thumb would be about every three days. Outside in a pot, you may want to water it more often. Like every two days depending on outside tempertures (higher temps will dry the soil out faster). Dont let the plant totally dry out, another way to test it may be for you to lift the pot, feel the weight wet (and drained well) then feel it two days later then three. It should be lighter, quite a bit lighter. You dont want soggy soil, and you dont want brick hard dry soil either.
"and on the part where i have wet soil, pretty much just don't water it until it's dry for the most part? if not, how do I switch it to dry, w/out killing it...(if that is even possible)"
If it is so dry it has no weight,put it in a bucket of water, hold it down (the pot and soil) untill the air bubbles stop or it feels wet. I hope you are not yankin' our chain here. Then just water it regular, like a house plant, with water. The rythm is water, let drink, water, let drink......It should not be this hard.....water the plant, let it dry out for a few days, then water it agian.
Try Grow Big by Fox Farms untill your girls turn to flowering. Then maybe Big Bloom by Fox Farms. You can get them in smaller bottles, bout quart size. Not to pricey, I cant remember exact price. They are both organic too. Ace hardware in my area carries them.
Resize your pics in your photo Edit on windows. Go to Image, then stretch and skew, when there make your photos about 30 in both stretch and skew. That should get you small enough to post here.
If your girls dont make it, dont get discouraged. Try agian, your second and third and fourth grow you will still be learning. There are many here who will help, but you need to read some more in the growing part of the "Marijana Cultivation" part of this forum.
As for aphids, try the "Sick Plants" section, pick them off if you can.
