Ok so after a while, i realized that the place where the plants were growing, were only getting a half day of sunlight. I have moved them to a new location where they are now getting a lot more :>

They are thriving!
However... I found out nigel was a male. I ripped it out and fed it to the dogs. I transplanted nigel to a new pot with a very sandy type of soil. Nigel is the plant on the left. Robyn and Sasha are now proud, single females :>

Just to recap... in order from left to right:
Nigel, Robyn, Sasha.

The ferts I am using a natural product called Seagrow, which you can mix with your water. there is no risk of over feeding the plants or damaging them with seagrow... decent stuff. the stuff stinks like ass though...
