The spots did not show up till today, the pic of plant that is like half green half brown was one that the fan was not reaching very well, so it may be heat related. The other plant that just has little spots, that leaf was touching a bulb since yesterday and the problem didn't show up till today. I have set up a new "space" so that air can circulate better and the fan can clear out all that hot air with ease so the plants won't get hot. I need some input as to whether this is a burn problem from the lights, or whether this has to do with the soil/watering area. I let tap water sit for a day, and then I added some water conditioner solution that I got from the fish section at a pet store. So I feel like the water should be ok. The soil is some perlite, with a little peat moss, and some filler soil from my mom's garden.

4 CFL 27W Bulbs 6500k spectrum
I have some reflectors, but use foil on the sides as well.

Any and all input/tips are VERY welcome! I do not have ANY money to spend until about a week, so I have to work with what I have...
On the side I have miracle grow fert, top fin water conditioner, a spray bottle for watering, and MG transplanting/rooting solution.

ok first you should get a thermometer the temperature should not be too high anything over like 90F is too hot... second get rid of the foil that can cause burn spots from what i have heard. Third what is "water conditioner solution"? lol whatever that is don't use it...if you have to use tap water then yeah let it sit out for 24 hours but don't add anything to it like that besides nutes if u have any... I would just use only water for now until they look better. Make sure the lights aren't too close to the plant give them at least a few inches.

The water conditioner is a product that makes the water safe for fish. aka removes chlorine and other harmful metals and what not from tap water, i heard somewhere it could be used to help make tap water for plants so i figured here goes! None of the spots were there until earlier today so I hope it may have just been plant proximity to lights and not the water/soil...thanks for the advice man!
