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.

Root rot?I feel I made a huge mistake. The last two weeks I suspended the top bloom fertilizer and star to give a considerable amount of organic molasses (at EC=1.4). The soil turn compacted, and leaves begin to yellowing. Is the plant showing signs of root rot? What should I do? Help!!

I need help troubleshooting weak plants! I think the clover might be the culprit but what do I do?Can anyone tell me what’s going on with these plants and what I can do? This is my first grow. I can already tell the seeds are growing slow because other seeds I planted in smaller pots are growing much faster. Any advice would be greatly appreciated!

Dried Leaves, Lockout or Stress. Week 5 of FlowerPlants suddenly wilting & looking crispy like they're dry, but pots are HEAVY! Suspecting root suffocation/rot ("wet feet"). Hard soil crust might be blocking oxygen. Roots are drowning & can't drink. It just happened yesterday since they look dried. Temp is 25C and Air 50%

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?

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.

What deficiency is this?Earlier, I added Epsom salts to fix purple stems, I’m pretty sure I over did it and I think this is a potassium deficiency but I’m not sure. I was being cheap and didn’t change res b4 moving over. Now that they moved tents, seems to be getting worse. How do I fix fast!? Pix in di
