Hello all! I have three cloned plants in 2x4, the sick middle one and the one on the right come from the same mother. They are in the second week of flower and lights were changed to 12 hours.
Background info:
- 3 clones, 2 from same mother (photo-period).
- On 12 hours of lights right now (2 weeks in).
- Autotpots with 100% coco.
- Keep the reservoir PH around 5.6-5.8
- CalMag + Canna A & B + Canna Boost being used now ~ 1.6 EC
- DLI for 12 hours is now at around 32 for center plant a little lower for the others. I lowered it a little a few days ago, I think it was in 36ish range.
- Middle plant is showing lime greenish, yellowing from top down. Bottom half of middle plant has normal color.
- I keep the VPD around 1-1.2. Temps are about 75-78F and RH is around low to below 60%.
Trying to figure out if the middle one is having a deficiency problem or maybe a too powerful lighting issue (gets the strongest rays). How would you go about troubleshooting this? Thanks again for your help!
