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.

The leaves are yellowing, some are turning purple, maybe it's normal or maybe not, I don't know. If anyone could give me some suggestions. I decreased the light intensity to 75% because unfortunately I can't raise the lighthouse.

Little seedling having a hard timr
So guys; I'm worried about this seedling. She's having trouble on keeping up with her sisters. I noticed a yelow color on their tinny tips 🤔 Cotiledons got brown pretty quickly too. She took longer to "open" the cotiledons after popping from the soil. Should I do something?? 🙏

leaf tips #2
Hi, continuing the previous question. pH runoff was 6.1 So I decided not to flush and gave it CalMag. Since then yellow tips doesn't spread any further, but the fan leaves on lower branches become fully yellow and died. Does that mean problem is getting bigger and I should flush?
