Yeah I think the light cycle can be an issue they need a break from those bright leds. I have a timer but I need to add an adapter since it’s two prong not 3 but I do have another timer that you control through WiFi that’s way better I know I have it stored somewhere I’ll find it. So what I think I should do is if it’s a ph problem since I’m growing in coco I’m going to purchase “cleanse” from Athena, since it cleans up salt build up make sure I wet the medium all the way until I get a ton of run off but I’m not sure if I should run cleanse with nutrients or nutrients. When I water I usually Ph around 5.8-6.0 In coco. I think another factor might be letting the medium get too dry between waterings.
