3 months agoAsk a Grow Question Had a question, first time grower on my second round. I’m in Flower week 3 and just noticed some early signs of powdery mildew on one of my plants. Guessing it’s because I have 7 plants in a 4×4 which I knew was definitely a tight squeeze. Just wanted to get any opinions on what to do. So far I removed the plant from the rest immediately and removed another that was straggling behind the rest leaving only 5 plants in the tent. Just don’t know what to do about preventing the other plants from getting the mildew as well. Don’t want all my hard work to be for mildew. Any recommendations on what to do to make sure the rest don’t go down the same route??

Would definitely take the rest of the girls out of the tent and make sure you quarantine the ones you think are alright, but just to be sure get a jewelers loupe and really analyze those leaves and then get some hydrogen peroxide/ water solution and really clean that tent and the equipment out being that the mold spores may be airborne already. As far as the infected plant there are some foliar sprays you can try out but just try it on a few bottom leaves to see how they react and then just make sure you keep her isolated somehow and keep treating her with either the foliar sprays or there are some home remedies like a tbsp of dish soap to a gallon of water and spray on the infected areas

This early on flower, would you use a fungicide spray?
And then sanitize the tent?
Late late stage flower you could bud wash with hydrogen peroxide

Fungus is environmentally preventable. PM, bud rot, stem rot, etc are all caused by the environment being out of an acceptable range. Fungus loves both warm and cool environments but humidity is the most important variable. Never allow humidity to exceed 65% to prevent fungus. No treatment will help without fixing cause first.

Really appreciate it fellas. And definitely trying to keep the humidity at a stable 55% now that I know 60-65% H. was way too high.
