Please help me, I am a new grower. My brother in law talks me into starting this, an now after getting all the necessary equipment he is not giving me any advice. Says I have to do my own research. I understand. I look at hus plants they are dark greem, and full, and healthy looking. My plants are like a lighter green, they look as if they are wilting. I understand that this may be due to overwatering. I had a problem with Powdery mildew, I bought some type of sulfer solution, I used it twice once about 8 days ago and then again today. Now they look really sick, what should I do. I feed them nutrients, with additives. But they don't look healthy at all. I am scared to put them into flower even though I know they are ready. Please help, any advise will help.
