Leaves turning yellow and burning - Nutrient burn or Nitrogen deficiency?
danielvt32started grow question 3 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.

Grower questionAny ideas what the issue could be?
Few weeks into flower. Dealing with fungus gnats and have kept the population very low.
Temps do get high, at most 95 (hot I know). I cranked down the lights to their lowest setting (100 true watts LED).
I have adequate air flow.

Leaves Turning Yellow - RQS Watermelon AutoHi GrowCommunity! I am currently growing a RQS Watermelon Auto. The plant is in week six and started flowering two weeks back. I did some LST which the plant handled quite well. I am seeing leaves turning yellow starting from the inside. Is it missing nitrogen? Thx in advance..

Surplus or deficiency?Can't tell if there's a surplus of nutrients or a shortage of potassium? One plant looks like nitrogen burn and the other two look like theyre maybe a little k deficient. Was thinking of chilling out on the feed on the burnt one and just feeding micro to the other two. Thoughts?

Yellow leaf tipsHello,
I think I have a slight over-fertilisation.
Could someone have a look at this. And could someone explain to me in this context whether and how bad it is that the water does not flow through when watering. I have never had water under the pot.

Possibly Potassium Deficient? Based on ALL the pics I could find, but not sure.I noticed these brown splotches and leaf edges on one area bud and pistils of my Orange Sherbet last night. Based on what I can find online, this might be potassium deficiency?
This is mostly on one spot near darkest edge when tent closed. Thanks!
