Issue: I noticed over the last day or two that some new leaves are yellow/brown in the middle. The older leaves all seem healthy and fine.
- I’m growing a few autoflower plants in an indoor tent.
- Over the weekend I had a power outage, so they were in the dark with no ventilation for 24-36 hours.
- I’ve also begun adding a little fox farm grow big nutrients to their water every couple days.
- I just raised the light to ~24" above the highest one, but it was perhaps too close before
Any thoughts on a diagnosis here? Ways to fix? Thanks!
