What it looks like to me is:

* Leaves are curled cause of over watering. The trick when it comes to watering is every 3-4 days or when you put your finger a knuckle deep and if it's dry to the touch water it. When do you water your plant?

* Lighting. Now as far as your plants looking spiney some if it's due to the FIM but most of it's the lighting. Now here's the question I ask. What type of lighting are you using and what's the Watts, Lumens, and type of Floresent is that. Now to help out I would go get a few 26 Watt cfls from walmart for $5.65 to help, but when u look for them make sure they say soft light, you warm the warm light for flower.

Now once we know we can help point you in a better direction.

Have fun be safe!
