So let me get everything straight Latewood:

I should add 1/4 tsp of superthrive to a gallon of water, and water my plants thouroughly after I transplant them. Correct? No other water soluable nutes? Because, like I said, on two of my plants, some of the leaves are starting to turn pale, and eventually yellow.

Like I said, they are starting their 7th node, and on top of that, the 1st node, 2nd node, and 3rd node, all have new growth shoots on their 3rd node. So, they are growing fast, and need food.

So, assuming Superthrive is all I give them, when do I start feeding them "real" food? Would peters all purpose 20-20-20 be good? Like I said, I wanted to go organic, but it looks like that won't be a good idea, no?

Oh, lol, and by "big square pots", They start out as a small square at the bottom, but gradually get larger, but still stay square, lol. Someone posted a thread asking if they'd be alright, and I believe Stinky Attic said they are the best to use, plus I think they are quite cheap.
