These (like the rest of the pics) are taken with a mobile phone camera, pending an issue with the real digital. That should change soon.

The HID light spectrum causes the pic to be a little "wavy." Hope I don't give anyone a headache...

The close-ups are of nute burn of some sort. The pH in some of the buckets got higher than the rest of the system, so I think some valves - as per Crispi are in order.

Please let me know what you think
