This looks like it could be ph lockout . Try flushing your plant and see how she does

Hi! Check on "tobacco mosaic virus". The yellowish stains could be signs of it. Good luck!! :)

Kind of looks like very weird Potassium excess. Could be a form of PH lockout.

Idk what went wrong
My Special Kush 1 is on week 5 of flowering. 4 days ago bottom leaves started yellowing, yesterday i watered and checked runoff ppm, which was 5000! So i decided to flush. Kept watering with tap water (PH 6.8 ppm 300) until my runoff water was 600 ppm. What your opinion about it?

Yellow leaves - new growth dark green. As health improves, can I expect yellow leaves to turn green?
Once a leaf starts showing signs of ill health (yellowing, etc), what is the point of no return? I have been working with this plant for a couple weeks and can't seem to get the yellow leaves to "heal" - new growth seems healthy to me however. Any thoughts?

Light burn
I've got what I think is light burn. I can't dim or raise my LED lights (300w), but I'm currently running them 24/0. Would switching to 18/6 help? Or would it help to take the burned plant and have it out in natural light during the day? I'm growing autos and they're flowering.

Calmag or Potassium deficiency
Starting to show hard yellowing on plant #2 looks like it can be calmag Deficiency or Potassium Deficiency. I gave them a bit extra calmag a few days ago and it seams like things are not improving too much.

My dear fellow growers, I've just started growing with no experience and am experiencing some leaf issues. I'd like to ask for your help and sugg
The plants in the photo were planted on August 15th, and they haven't bloomed yet. I have very little knowledge about fertilizing, so I applied fertilizer every time I watered for the first month. I'm growing 9 plants in a 120x120cm tent and using two 240W full-spectrum lights.

Nitrogen deficiency but why?
My Critical Auto is more and more wilting and yellowing. Most likely due to nitrogen deficiency. Some have red tips on . PH of soil was normal, how can I make sure that it's not nutrient lock anyway? Should I flush it nonetheless? Feed it more? More info in my diary.

Is this sign of deficiency, to close to light, or toxicity? If so any ideas how to fix? Thinking of attempting a flush later??

Vexatious yellowing I can't get to correct.
This Northern Lights auto is being vexatious...I can't get rid of the yellowing towards the bottom. Not overwatered, I've tried beefing up the nutrients, etc. with no effect. Any thoughts or do I just writing off as she's just being a jerk? Other plants in this grow are fine.

Starting to yellow
So I had good growth up until 2 days ago when the one plant started to yellow. I had them going 24 hours a day and I got grow dots mixed in the bottom two thirds of the pots. Could this be light stress? or could it be hungry?
