Leaves turning yellow and burning - Nutrient burn or Nitrogen deficiency?
danielvt32started grow question 2 years ago
Lower leaves burned and curling. I was convinced it was caused by overfertilization but someone brought to my attention that it could be a case of nitrogen deficiency. First time growing. How do I fix it? Do I cut all the burned leaves?

She also looks slightly stunted, but likely in a week or 2 she should recover

Looks like over watering, ph, and a deficiency or lock out

Cut the one's that are over 50% damage, and feed it only ph water till she recovers. Good luck 👍

Need to know more about your watering/feeding to narrow it down.
Ph and EC or ppm
Frequency of watering
What are you feeding them?

That is not a N deficiency. Your lower leaves would be fading from green to yellow. That is a burn of some sort.
Seeing that there isn't tip burn im guessing pH issue possibly? Could also be over watering. Lemme check some charts.

What to do? Leaves are getting worse.Had some light strain earlier on, but now im leaning toward a deficiency. Been feeding on a low-dose flora series schedule with clean ph water for every other feed. Just had clean water yesterday and nutes 3 days before. Dry out between feeds. Nitrogen? Calmag? Other?

Magnesium deficiency?I think I may have an early deficiency of magnesium? I'm totally guessing here. Not much experience. Seems to slowly be getting more pronounced.
First water since transplant to FFOF was only pure RO. Thinking maybe I should added cal-mag?
