My first [recent] hydroponic grow.

I got kinda laxadazy taking pics this week sorry. The 23rd is day 4 of week 4 so 4 days of growth from the last pictures. So, the leaf problem is back and I am now certain it's rust fungus. Going to clip off the badly infected leaves , spray with garden safe fungicide, and I think I will switch to 24 hr light cycle for a couple weeks, applying the fungicide in another week or so. It's just affecting the blueberry so far but I will spray the pineapple to be safe. The girsl are still fine as far as I know but humidity is very high and I am out of town so hopefully I can fix the issue before anything bad happens to them. Lights still on 24/7. Will be cutting the light time when I get back. -Jul 31
