Problems with plant

Hi, on saturday my plant started having brownish and shiny leafs, but i ignored the problem(it wasn't so serious) and I lowered the light(250W hps) from 50-60 cm to 30, I was gone till monday, when I got home, i saw that the plant was looking horrible, so I put the light at 45 cm from my plant BECAUSE I did the hand test and I was not feeling heat at all, after some hours, my plant was looking worse, so i did some research and the plant can get burns from fan stress, my 35W fan was always on blowing air on light and plant, so i reduced its power(I still don't feel heat on plants top when I m doing the hand test)

My plant had and has the following problems: shiny leafs, taco leafs lol, some leafs are brownish, leafs with transparent/black/yellow spots annnd it is growing slow
