Leaves turning yellow and burning - Nutrient burn or Nitrogen deficiency?
danielvt32started grow question 4y 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 could be causing this?I'm experiencing yellowing, browning and crisping on some leaves, but only on the main colas so far.
I have checked the PH in and out. In has always been perfect, but the PH of the run-off was 5.8 so I'm flushing to rule out nute lockout.
Anything else it could be??

Deficiency?So I noticed this yesterday and I'm struggling to figure it out. The symptoms only appear on a few leaves of only 1 branch. Nothing about the environment or feeding has changed. A recent flush of plain pH'd water showed slightly acidic soil but not too crazy. Bottom feeding with

Yellow Burned Bud Leaves. Purple Calyxes. Red Stigmas. Stunted?As u go from top of canopy to bottom, the leaves get darker green and less burn. Lamp is at top of 3ft tent, 10 inch above canopy. Feed is at 1.3EC/6.1ph. Runoff EC climbs, then I FloraKleen flush about once a week. So is it just light burn? What you see? Is she stunted? Thx.

2 Yellowing Fan LeavesI have 2 large fan leaves from the main cola turning yellow and 1 almost looks crisp or burnt on the edges.
It is only 2 of the leaves and by my reckoning, they are 2 of the oldest leaves on the plant.
From research, it could be the bump in nutes or water issue.
Any ideas?
