Here we are, 3.5 weeks into flowering and I am getting the issue of yellowing upper leaves accompanied by brown spotting within those leaves. Some leaves are green w the spots so I'm assuming the yellowing ones are the more infected.
Some background:
Strain: nirvana northern light autoflower
Lights: 250w HPS. 2 65w CFLs
Soil: ffof
Nutes: fox far trio, supplemented dolomite lime for cal mag boost
Light schedule: 18/6
Temps: 70-81 F
Humidity: 35-42%
Ph of soil: using the drop method with runoff I get a solid 6.0 reading
I always test my water ph to around 6-6.5.
This is my first grow n I believe I'm halfway into my flowering stage. So not sure if I should just ride the next 3.5 weeks out or find a solution.
Look at the lower left leaf for spotting/yellowing
spotting/yellowing in newer growth
Top of plant has twisty new growth(only 1 of 3 to have twisty growth like this)
