Here are some pictures. These are in hydroton fed 4 times a day and off at night.

Water temp < 65
Air temp 78-80 day and 74-76 night
PH 5.5 and rising due to pythium issue from past.
running strong nutes and thought I had enough cal-mag going but maybe not.

Can you confirm that this is cal or mag deficiency?

Thanks!
