ive notice this greyish kinda powder looking shit on the top of some my leafs and was wondering what it is and what i should do about it,
Just to let you know i didnt write the following text, i just pasted from another thread so here goes "You have powder mold. I have dealt with this a lot in the past because I grew Maui Wawi which is very suseptable to powder mold. If your plant is past week four of bloom seperate the infected plant so it doesn't affect your healthy plants. There is nothing you can do to fix the problem once you have gone past week four of bloom. If you haven't past that point you can go to any grow store and buy mildew cures, most work well. It is vital that you spray the entire plant with the mold cure(both sides of the leaves) IN THE DARK. I have even made a large mixture in a clean trash can and fully dipped my plants in mildew cure. If you don't want to spend any money, I have friends that swear by baking soda and water. Mix baking soda and water in a spray bottle and foliar spray as usual. They say this has cured their powder mold in the past. Hope this helps. I have successfully beat powder mold, good luck to you..." Hope this helps man!
You should probably get more opinions but if it is powdery and white/grey then its likely to be powder mold
