2nd batch

Hey there IslandP Regardless off the source of mold/smell if you were wanting to harvest these plants after that I would highly recommend looking up a technique called Budwashing. Essentially you take your fresh cut crops and dip them in a bucket of water with a small amount of hydrogen peroxide. Then dip them in a follow up bucket of cold water. This method is known to help clear out some forms of powdery mildews and pests. It also has the advantage of cleaning your buds of dust/hair (you would be surprised how much they gather after 4-5 months) for a much cleaner and smoother smoke. Hope that helps you come harvest time 😎

I may be a little late to the party but I'd go with mold/mildew looking at your pictures. Any foliar sprays could make it worse. If its bugs go for a natural predator like ladybugs. Its its mold ot mildew try and wipe it off with a dru cloth then get a good strong floor fan blowing from below up into the plants. Could be a good idea to try and train the plant out wider too so you dont gavs buches of leaves and buds touching each other. Just my thoughts. Apart from that your grow is really great and I'm going to follow from here on out! Good luck!

Hello @IslandP . Spray every 4-5 days for at least 3 times and spray all the plants. Another good way to fight meal bugs and scale bugs is a potassium salt spray. Happy growing ! 👊
