here are my latest pictures. im getting a few rust spots on the pure gold. I fed them last week and these were taken today and i gave them strait water yesterday. The ph runoff is normal, around 6.5, but i was gone for the night and the power went on and off and it turned off my ventilation fan. when i got back the temp. was 85. Any thoughts on if they are nutrient burns or light burns. The plants seem to be doin fine.
