So, I am currently having issues with yellowing and small amount brown my leaves. The plants are 3 weeks into flower and began to yellow last week. I've hit them with water phd at 6.0 and guano tea for nitrogen and nothing really changed, what could this be? My room temps stay between 68 and 79 , I have good circulation, and room is super clean. image.jpeg

It is possible that you simply didn't supply enough Nitrogen during the transition period which is basically ending now. Typically we address this known problem by not switching to bloom nutrients for the first 2 or 3 weeks into the light schedule change. So is it possible you jumped the gun on using bloom nutrients? The last thing you want to do to a plant in flower is give her too much Nitrogen as it is known to stunt bud development. You didn't list your medium or nutrients so it is tougher to understand if you are missing something in your schedule.

Alternatively the problem may be that you are root bound and I find myself wondering how long those plants have been in those planters. If the plant is out of room in the root zone I usually see yellowing leaves all around the plant like that, the plant is having to kill leaves in order to make buds. This is a strategy plants use to make seeds since you need roots to support an equal amount of foliage the plant will kill off leaves so it can use those corresponding roots to make buds instead.

Definitely not root bound, only been in those containers for about 1 month, a week before going into flower cycle. I started bloom nutes about a week ago, so about 2 weeks after transition to 12/12. I use coco coir as my medium, and heavy 16 bud A &B, AN voodoo juice, AN big bud, H16prime, fire, finish and some cal mag.

Cannabis is not a magic plant that needs all that stuff. All you need is a good balanced nute with all your macro and micro nutrients.

A even number 5-5-5 or 10-10-10, 20-20-20, etc. If the numbers are off by a number or two that's fine.
