This is the photo of it

I can't tell for sure in this picture, but it appears the soil is highly water retentive and that may account for the brown spots. Searching 'gritty mix' should provide useful info. As to lighting, a cfl grow bulb at 6400 or 6500K should be great. I would keep it closer, 3-4 inches, and provide air circulation.

What is the plant bulb you have currently?

And what is the fixture rated for?

It is a 60 watt incandescent. The fixture is actually a heat lamp so it is rated for 250 watt

Currently 18 in from plants but will be lowering it to 12 tonight

I recommend using an infrared thermometer to check your leaf surface temps when running an incandescent - make sure you don't cook them.

CFL is much much better, as it is more efficient and the wavelengths of light is much better. Try to get a daylight balanced bulb 6500k with the maximum watts possible (less than 250W, of course).

There are 125W CFL bulbs out there (actual, not equivalent) which put out a good amount of light. Many around the forums are using them and may be able to recommend you further.

Thanks

I agree with ewwmayo about soil - while they are in individual pots, they are covered & surrounded by too much soil for any 'breathing'. Good idea to begin with, but would probably work better if the 'fill' was gravel rather than soil. If you were to re-pot them into well draining mix and fill space between the pots with gravel, you should be able to water generously, with excess water draining away rather than in 'sips'.

I am assuming there is good drainage from the main container (looks like pieces of slate forming a container, sitting on a bed of gravel/rocks?)

The light is definitely too weak, 60w isn't enough at all but you can't put it closer because of heat. I have many CFL bulbs, 100 & 125W (equivalent) and they are much closer to plants.

tiny plants should be in tiny pots.
