Hi all, First post here. I was hoping somebody might help me out. I am growing 'the ultimate' http://www.pickandmixseeds.co.uk/products/dutch-passion-the-ultimate I have a room 3 ft by 7ft with 2 x 600w HPS. I am growing in compost in 10 litre pots. My thermometer stays between 20 and 30 degrees centigrade. I am using canna terra nutrients, vega for veg and flores for flowering. I also use canna PK 13/14. I am using 5ml per litre of the flores and 25ml of the pk 13/14 per 15litre bucket. Most of the plants are fine, nice compact bud production, but I have a couple of plants that have grown taller than the rest and the buds are really straggly and thin. All the plants were started within 3-4 days of each other.
I know I'm not supposed to take pics with the light on, but the leaves are all the same colour on all the plants, which is a healthy darkish green. Here is a pic of one of the OK plants:

And here are a couple of the tall lady:

These were all grown from feminised seeds. I put them into 12/12 about 5 1/2 weeks ago, and the first hairs started showing about 1 week later. I feed each plant about 750 ml of water with nutrients per day. I have 11 plants in the space, so they are all touching their neighbours.
Can anyone suggest what might be causing this problem?
Cheers.
