I have an HPA Aero setup with a recirculating reservoir and I'm coming towards the end of week 3 of flowering and I have signs of nutrient deficiency but it's from a high PH. My PH is about 7.0 - 7.5. I have been adjusting the PH in the morning and by early evening it's back up at the 7 range. PH was perfectly fine until the end of week 2/beginning of week 3 of flowering. The sun leaves seem to be dying more so than any others. They start with a slight light green/yellow then brown edges and die.
I'm using:
RO Water
Full line of Aqua Canna Nutrients
Cal Mag
Snow Storm Ultra
Aqua Shield
Running about 900PPM
Roots look perfect
No signs of pest or disease
Running 5 sec on/4 min off
Rez size = 10 gallons
Changing Rez every 2 weeks
Rez temp = low 70's
Air Temp = mid 70's
Humidity = %50-%60
1000 watt HPS
Any ideas on the high PH? My girls are dying!
