Another question
Hello everyone! 😊
Sorry for all the questions, but this is my very first grow, and I’m still learning as I go!
About a week ago, I noticed some strange marks on one of my leaves. Since it was a leaf I was planning to trim anyway, I went ahead and removed it.
Now today, I noticed a different kind of spot on another leaf, and I’m starting to get a little worried. 😩
Does anyone know if this could be caused by a bug or pest? And if so, what’s the best way to get rid of it without hurting my plant?
I’m still new to all of this, so any advice or guidance would be greatly appreciated! Please be kind, I’m learning! 🌱💚
Thank you all so much for your help!

This looks like beginning of nutrient burn to me. Your root zone EC is likely starting to tick up.

What does that mean

u/BlackAssassinOfFate 9d ago
The level of salts (nutrients) in your root zone is likely starting to build up and not get fully flushed. Are your roots in coco/rockwool or sitting in water?
EC is electrical conductivity. Usually used with coco/rockwool substrate to measure nutrient level in the root zone. If in water, ppm is a common measurement

Roots are in water and PPM during last water change was 325

325 is low, in veg I run 6-800 PPM. I ramp up as flower goes on by week 2 12-1600, if it’s a kosher kush cross, 18-2000

We are into week 3 of flowering do I increase the ppm all at once or so much every few days

La primera imagen simplemente tenias una pequeña deficiencia de calmag amigo quizas sumado a un vpd algo elevado que te ha “sacrificado “ unos cuántos estomas, en realidad no es nada peligroso simplemente necesitabas un pequeño ajuste, en la segunda imagen aunque no se ve muy bien a simple vista parece una pequeña plaga de trips ten cuenta con eso… eso si me preocuparia mas que una pequeña deficiencia o estrés ambiental, por lo demas se ve bien bonita bro
