What do you think the problem could be?
Micro_greenstarted grow question 9 months ago
There’s something going on with some of these plants and I can’t seem to identify the problem so far. I have been doing a lot of research and I’m in a process of elimination at the moment but the plants growth hasn’t been affected. I will continue to try treat the problem.

Looks like the leaves have been wet under the light being on. When I had issues exactly like this it was russet mites. Which are crazy tiny. Need 60x to 100x magnified to see. I soaked (30 min), and rinsed my whole garden about every other day for a week with neem oil mix. It eliminated the issue, and has not been back since. Looks like it is spreading to other plants as well.

Kind of looks like a potassium deficiency to me. Based on it having more “blotchy” looking markings of yellow opposed to if it were an Iron deficit the whole leaf would be turning yellow.
Potassium also starts in the newer growth as well so that’s kind of the only thing that resembles the same markings in your plant.
A pure potassium plant solution would help as long as you follow the directions. That way you’re not having to over do your other nutrients. You can also use potassium as a foiler spray and plants love it. Mr. Grow It uses a potassium spray during veg on all his grows.

No creo que sea deficiencia de nitrógeno. Por que su problema empieza desde la parte superior de la planta. Y la falta de nitrógeno empieza desde la parte inferior.
He investigado un poco y llegué a que puede ser carencia de hierro.
La carencia de hierro suele deberse a un pH (básico) demasiado alto, y puede corregirse limpiando el medio con agua con el pH correcto, y si es necesario, se puede añadir un suplemento de hierro. El hierro puede reaccionar con otros nutrientes y provocar problemas propios, por lo que es importante ir con cuidado y observar todos los cambios muy detenidamente.

Why are my plants leaves so bright green/yellow?Wondering if anyone knows why the plants might be looking as light green as they are? We are running a purely organic grow and have not added nutrients beyond the super soil mixture. Wondering if anyone has any tips or suggestions, thanks!

Leaf diagnosis: nutrient burn or deficiency (or both)?he leaves with the burnt tips appear to be more prominent at the top of the canopy, only affecting new leaves. A handful of these leaves look a little twisted. Meanwhile, the yellowing leaves are more prominent in the middle of the plant, just below the canopy
