Im sorry to hear that, hope you could save most of it. One thing i e learned growing is when things go wrong its always at the worst time, right before harvest. And i get it, itvtakes time to acquire the problems that haunt us most. So until i learn ro read the plant like a book(without using cliff notes lol) i try to stick to plants with natural resistance in my case to molds because im on the coast in a beach city and there are also tons of citrus trees everywhere so powdery mildew is just in the air certain times of year. One strain i have had particularly good luck with is lemon kush and another being blue dream. Seen other plants rot around them and they just power thru. Now that im getting into autos i need to find those strains thatbwork for me now in my current setup! And have those same traits that helped me pull thru with said strains when everything else turned to grey trash. I am currently growing out 5 strains and hope to run multiple strains from here on until i find those genetics tht just work for me. So for now, i will be on the hunt for unforseen future. Its work that i enjoy and im excited to see those frosty green goddesses doing their thing in my garden!
