Ebb & Flow Bucket System
Rooted Clones have now been vegging 28 Days
Ph: 5.7
PPM: 1350
Res Temp: 75
Room Temp 65 - 82F (w/ C02)
2 Hoods, each w/ 1,000W Dual-Arc Bulbs on Light Rail
Each hood covers 12 Plants
Approx. 7 Days ago some plans started to exhibit brown spots. My temps were spiking up to 86, so I sped up the fans and dropped them down to 82. I also added some more water (RO) to thin out the nutes in case it was over fert. No dice.
I was using Fox Farms - a buddy suggested trying a different brand as there are occassionally issues with FF's Big Bloom. Another buddy suggested it could be magnesium def. So I flushed the system with PH'd water for 24 hours. I then ran it another 16 hours with PH'd water (30 Gallons) and 1 cup dissolved epsom salts (for mag). No change.
I switched brands of nutes (a local brand, I've heard good things) last night. It's a 3 part blend (Micro, Grow, Bloom), with some seaweed, batguano, and 0-50-30 boosters. I also use a little (3/4 cup) SM-90 for root rot and 1 Cup Cal/Mag (since I'm using RO water). I filled up the res last night at 75% strength based on their schedule for veg week 4. It's not getting better, and if anything it's a little worse.
I've lost 1 plant to this, and now most of them are starting to be impacted. It looks like it starts in the middle leaves, and then spreads up & down.
Advice Please!
