It got really bad after I drowned them with a Strong Brix Spray and my temps were hitting the high 80s with very low RH like in the teens or low 20s so I am pretty sure that was the cause. After that is when it started fading. Also all the plants look like that so I am thinking it was an environment issue not anything from the kit other then me not using the Brix Spray properly. I soaked them down top to bottom, They were dripping wet. I also sprayed the top of the leafs and put them right back under the lights while they were still wet. I will not have the heat issues now or low RH I got a better Humidifier so my RH is much better now and I am venting the air from the carbon filter out side now so heat is no longer an issue
