What kind of deficiency is this?
Ezzjaybruhanswered grow question 5y ago
I believe this is potassium deficiency.
K deficiency causes internal temps of foliage to rise and it causes the protein in the cells to burn and degrade. Usually happens on the edges of the leaves.

Little seedling having a hard timrSo 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?? 🙏

Floracion con problemasI don't know what I'm doing wrong, I measure EC, pH, and water temperature for irrigation. What's going on here? Irrigation pH 6.4 EC 1.4 temperature 19 degrees. Reddish stems, wilting leaves, I've watered with flowering fertilizers but it doesn't improve. I plan to water with plenty of water and measure the runoff.

Droopy leaves, weird spots.Does anyone know what's wrong with that bottom left plant? Those spots appeared pretty soon after I cleaned those filters. I'm thinking that it's a stress caused by that cleanse, no chemicals or such were used, but some roots were torn in the process. Deficiency? Disease?
