They could be burns due to a high amount of light, heat, or maybe caused by foliar applications. I recommend separating the lamps, using an EC of 800-900, and a pH of 6.2.

Harvesting a struggling plant or just letting it fight
Can she be saved or just flush her and harvest what I can? She doesn't appear to be happy. Has some CBD genetics so the lack of trichomes don't worry me. Rest of my garden is fading as well. Flushed em last feeding and they didn't seem to like it.

Yellowing dry leaves, late flower.
About 2 weeks from harvest time, the yellowing leaves which I put down to an early fade have become dry, brittle, curly and splotchy. Should I worry this late? Is it potassium defeciency, lockout? Should I begin flush? Add molasses?

Yellowing leaves.
Accidentally resolved my original question instead of liking a suggestion and I cant change it 😅 Same issue still applies for now. I have been testing the PH going in but not out so I will try this and pass on my results after the next water 👍 Open to all observations.

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

Nutrient lockout, ph imbalance or nutrient burn?
Unfortunately I don't have a ph meter, so my best guess is one or more of these problems: nutrient lockout, ph imbalance or nutrient burn. The first 3 photos are from an Auto Northern Light and the last 2 are from an Auto Jack Herer.

Esto es normal? Floración - Double cookies auto
I'm in my last week of flowering, and recently the leaves started turning like this very quickly. Is this normal? Did I do something wrong? I have 4 autoflowering plants that are in the same state. A lot of yellow leaves have been falling lately, but the buds aren't maturing.

What’s most likely causing this?
What does this look like? Soil ph seems good and I’ve been giving them light feedings of nutrients. Any possibility it’s a symptom from being root bound? It’s just a few leaves on the bottom of the plants.

Anyone know what's wrong with my girl?
Can anyone tell me if this is going to effect my flowers? Should I cut these leaves out? What can I do to correct it? I left a pretty good description in week 7 of the battle with this plant.

Dying leaves
I had some mild nute burn last week on a few plants. A few tips were burnt. Some lower leaves are turning yellow and dying. Is this still nute burn or something else?

She has yellowing and dying leaves issue for a while now. I was giving more nutes lately to combat the issue. Now burnt tips say it is to many nutes. So I decided yesterday that I should water with a bit of calmag before next feeding at beggining of the week.
