How often are you feeding? Every three days
If flowering, when did you switch over to using Bloom nutrients? 2 weeks into flower
What order are you mixing your nutrients? (example: veg nutes 1st, bloom 2nd ect)
What is the TDS/EC/PPM of your nutrients used? 1.2-1.4
What is the pH of the "RUN-OFF"?
What method of pH test was administered? Using Strips? pH pen?
How often are you watering?
When was your last feeding and how often are you feeding? Two days ago, every three
What size bulb are you using? 600W
What is the distance to the canopy? 25"
What is your RH Factor? (Relative Humidity) 30-40%
What is the canopy temperature? 73
What is the Day/Night Temp? (Include fluctuation range) 73/68
What is the current Air Flow? (cfm etc.) 300 m3
Tell us about your ventilation, intake exhaust and when its running and not running ? 2 x 6" outside air intakes, 1 x 6" exhaust into filter

Are plant's infected with pest's? Fungus gnats, a few plants have had PM also allthough not this one (treated with bacterial remedies)
Please help me with this Rhino. I'm guessing it's a deficiency but I'm not really sure. pH of feedings are always between 5.3 and 5.8.
The bottom leaves and a few big ones higher up are getting crunchy and yellow. It doesn't look only like N def since they get necrotic spots on the leaves and turn real ugly. Veins are more yellow than surrounding matter.
