Hello everyone so this is my first grow and I've ran into big problems this is 11 weeks since they sprouted. They're 3 1/2 weeks into flower and they are starting to look horrible my one is completely being taken over it has been for awhile but the other 2 were just fine until recently now they also are turning yellow with brown spots and dying. They are still getting buds but I don't think they're growing at a good rate anymore. I've tried researching and identifying the problem but I'm confused. Just hoping someone out there can give me some advice I really could use it right now. This is the strain Crystal. (White Widow x Northern Lights)
