Hey guys. Does anybody have an idea what is causing these spots on my leaves? These are OG Kush autos grown in FFOF/Nature’s Living Soil. The full details of this grow are below. Should I add some more Nature’s Living Soil as a top dressing to top up on nutes? Thanks for any suggestions!
Full details:
2 x OG Kush autos from Nirvana, indoors in a 4x4 tent
Age: About 6 weeks since sprouting
Soil: Fox Farm Ocean Forest with Nature’s Living Soil and perlite (“Living Soil” approach, not “Super Soil” approach)
Fed only water, a mix of spring and filtered drinking water that comes out at roughly 6.5 pH (I feed only water since I’m using living soil)
Light: Black Dog PhytoMAX-2 600 (615 watts from wall)
Temperature: Low 70s during lights off, mid 70s with lights on
Humidity: Upper 40s with lights off, low to mid 40s with lights on
Ventilation: 8” system with 710 CFM fan pulling through two separate large carbon filters (one tail end and one inline) through very long duct work, resulting in a nice breeze coming out in an adjacent room, and tent walls sucking in decently but not extremely hard
Small Vornado air circulator inside tent, blowing 24/7 on low, pointed slightly down to not be directly on leaves
