Hi Everyone! First time grower here, everything going well so far except for this little thing. 3 weeks in the veg state, outdoor grow (humidity ranges from 60% onwards, outdoor temperature is 26°C-28°C), roughly 12/12 light cycle. Fertilized it once, not at full strength though. Watered it whenever the soil was dry. The plant is relatively healthy, except for a physically damaged leaf. Unfortunately, I'm not sure about the strain because its bagseed. I have noticed tiny white specks on my plant. I would just like to know if this is actually powdery mildew, or if I'm just being paranoid. I've attached a photo of one of the affected leaves. In the case that it is actually PM, what are some safe treatments? Thank you!
Looks like it could be a little PM. You should transplant so the plant isn't so low in to the planter.
I didn't spray it with anything. Thank you for the advice! But how should I go about dealing with the mildew itself? Also, is the plant an absolute goner or is there still a chance to save it?
White Powdery Mold: Ruiner of beautiful plants.Remove White Powdery Mildew from leaves - Get some water (tap water works fine) and some paper towels. Wet the paper towels and use them to gently wipe the mildew off the affected leaves whilst being careful not to jostle any leaves with spores on them. Using a wet cloth will ensure that more spores stick to the cloth instead of becoming airborne. Note: While it isn"t necessary to use paper towels, their disposability helps to curb the spread of spores from one leaf to another. Ensure plants have proper airflow and ventilation - Even if you have absolutely no airflow or ventilation in your grow room, having even two fans will drastically reduce your chances of encountering WPM while also benefitting your plants overall health. One fan should be oscillating if possible and should gently blow air over your plants. All the plants need is enough air to gently rustle their leaves. The second fan should be in your grow room pointing outward, pulling heat away from your plants (only needed if you have no ventilation). Having a fan pointing out of your grow room will force old air out of the room, and in turn, pull new air into the room. At this point, you"ll have new air coming in, being used and circulated, then kicked out. Keep in mind that two fans is a minimum. Treat plant with SM90 to kill spores prevent future growth - Mix 1 part SM90 to 5 parts water(I"ve found 7 parts water to be equally effective) in a clean sprayer/mister. Wait until just before your lights for off for the day and mist your (newly cleaned) plants. Get all the leaves! This diluted SM90 mixed will kill any spores it touches, and anywhere it lands becomes uninhabitable for future spores. Plus, it"s safe to use - even during flowering - and it smells awesome.
That plant looks like it's growing in clay and unless you get some proper soil to grow it in, it's not going to do very well at all. These plants require excellent drainage and a light/arid soil is best for growing....actually, formulated grow soil is BEST, but if you can't get your hands on it or aren't willing to make the investment in it, you need to get some decent off the shelf potting mix and add about 30-40% perlite to it for drainage. NO NUTES because all store bought soils are LOADED with slow release fertilizers. Repot into a 1 gallon pot with NO reservoir on the bottom so you can see what's coming out at the bottom through the drain holes when watering. Go to the sticky's in the new grower threads and read up on the basics of doing this properly. You do not have mold but if you don't get some better soil to grow in and take a little time to figure out how it's done correctly, your plant's not going to do much anyway. And, always fill up your container leaving only enough room to manage watering without spillover. You don't bake a cake without a recipe so why try to grow something you've never grown before without getting directions on how to do it....especially something as special as this? LOL Good luck!
