Mystery bag seed

1L water, add a queeze of dishwashing soap (the green ones are the best), and a spoon of Denatured alcohol, also called methylated spirit. spray this solution. but the milk should to the job, i use 1 part milk on 3 parts water, worked with mildew and false mildew too

If milk dosen't control it. You can use 2-3 tablespoons of apple cider vinegar(5% acetic acid) to 1 gallon of water as a foliage spray. I would start with 2 Tbsp. every 7 to 10 days. Spray first thing in the morning before the sun comes up. Be careful using this if it is too strong it can burn the plant. Also try to defoliate some leaves to allow more light and air to the inside of the plant. Culprit is probably morning dew sitting on your plant. If shes small enough I would build a small frame out of stakes and cover her with some lightweight frost clothe at night to keep her dry.👌

Hey there, so the milk treatment is good. Remove any leaves laying on eachother, those trap the most morning/night moisture. As for treatments, green cleaner is very effective(agricultural version) and if added to neem oil it can fight for up to a month maybe longer. You can also use plain neem oil spray but you'll maybe want to wash off residue after a few days and not use too far into flowering. Also using a silica product through your whole grow helps to fight pm as well as many other things, potassium silicate etc. You could still use it now but definitely for future grows. Plus there's always the simple process of wiping the leaves also if the pm hasn't spread too far yet. If you made a mix of baking soda, water and a drop of dish soap that works also...pretty much any of the bicarbonates. Good luck, love the mystery seed batches ✌️
