Persistent brown spot leaves. Even more now. It seems only leaves in the center on top are affected. Not sure if it's because of the proximity to light (45,000 lux) or nutrient deficiency.
Two other bad things happened: my DIY DWC bucket developed a small leak. I might have to make another bucket if I can't fix this one.
Also, while doing LST to the main stem, I applied too much pressure and snapped it, about two inches came off :cry:
At that point I really felt like stopping all project and starting a new one. I'll keep it going for now
Made 4 gallons of the nutrient solution, 3 went into the DWC bucket, one gallon will be kept to supplement during the week
I changed the light off schedule: programmed to keep lights off during the hottest time of the day
It seems, I need to increase Flora Bloom during Vegetative Stage 2 (week 5 on my chart) - currently it's at 2.5 mL/gal, would go to 4 mL/gal next grow
For the first time today, my pH became too acidic and I had to use pH UP
Growing well. Starting tomorrow I will increase nutrients and add some more Phosphorus supplements
