Count the total watts going into the lights not what they say they are putting out in wattage. 150 watts will be your target for what your trying to do. I dont think you have enough light on that plant.

It appears you have 2 plants in one pot. This will come back to bite you squarely in the ass. One pot one plant - the roots dont play well with other plants nor do the leaves for that matter.

The soil may be getting too wet as well. Try watering every 3 days instead of every day. Nearly dry soil is almost as important as wet soil for reasons I wont get into here.
