What are these spots? I've tried Laser 2240 SC, Kumulus DF and Champ 77 WG and nothing works, the spots are still spreading.
High bro,
Haha gotta love your name!
The spots on your leaves are caused by calmag dificiency propably due overfeeding.
You can flush the build up nutrition out of your soil, let the soil dry out after and continue your grow with less nutes.
For flushing you need to slowly pour water onto the top of the soil, allowing it to drain freely from the bottom of the pot. Pour slowly, so the water doesn't overflow from the top of the pot. Use approximately four times the pot's volume in water to flush the soil. For example, use 1 gallon of water for a 1 quart pot.
After the flushing you want the soil to dry out (almost) completely. After this you can continue watering like you are used to and start giving a small dose of nutes again.
Happy Growing! π
So I'm at my fourth grow with the same setup: coco+perlite, a garland tray with an autopot valve, nutrients are GH Trio (see attached pic for feeding schedule). I use Ca+MG. Starting at week 6 the plant starts dying, and it's almostdead by week 12. It's the fourth grow with this.
I cant see any powdery mildew anywhere here my mate dont listen to anyone,powdery mildew is like a spreadout moth balls,your resin looks ok to me no mildew on your resin,look thru a jewlers loop,i would say you are harvesting too late-your growing northern lights auto? Your cutting way too late,dont keep them 10 or 12 wks once youve switched cut after 8 wks exactly now theyre established cuts ull see the difference,or go for genetice that finish 65-75 days that will take you to 12 wks yourself peace!
Because you are growing at 24/0!!!!!
All cannabis plants NEED sleep!!!!!!!!!
Go to 18/6 in future and everything will be much better!
Without sleep, cannabis CAN NOT finish its photosynthesis cycle and have a correctly functioning metabolism.
A plant with an incorrectly functioning metabolism will NEVER grow properly.
The MYTH that it is ok to grow cannabis for weeks/months without sleep needs to be removed from history ASAP!
Your poor plants are dying from exhaustion.
PPM is 310-330. Water temp in bucket is 20.1C. The reason I think it's a pest and not a defficiency it's because I've grown in the same exact conditions in a different location and didn't have any issues.
Haha gotta love your name! I think that mosquito is right and that this is indeed caused by broad mites
Here is a link from an article with pictures so you can compare and an explanation how to identify and how to get rid of broad mites.
