Rust spots on fan leaves
WILLIAMSII_Fr_Farmanswered grow question 6y ago
Hey buddy. I think it's a calcium deficiency. I had the same problem with my Quick Dinamed CBD, it showed up at the same stage and with extremely similar spots (check out my Quick Dinamed, you'll see what I mean). I made the mistake of thinking it was due to a phosphorus deficiency, which gave the calcium deficiency time to spread. You should add Calmag to the next watering, or you'll see all its leaves necrosing with light rust spots and then grayish ones, and it will happen fast.
I hope this helps you.

Phosphorous deficiency wich is also causing some Magnesium deficiency.
There ya go mate good luck.
If phosphorous and some calmag doesnt do the trick then its a fungus called rust, there a lot of organic options to combat this too, if its not the first option just google treatments for rust in cannabis. Its easy.
Good luck nice looking plant.
Stay lit growmie.

Are my leaves getting burned?Hi peeps, here's the thing.The "bottom" of my leaves started to look kind of like they're dry. The PH is perfect 5.6 for hydro, I worry that the super low humidity of around 30 has something to do with it. The temp doesn't get hotter than 27C, at night around 18.Water temp is 21C

Tiny White Bead-Like Structures on Surface of Leaves - February 3 (Day 30)My plants are beginning to grow tiny white bead-like structures on the surfaces of the leaves. They look like trichomes, but I am only in week four of veg. I want to make sure this isn't some kind of mold starting. Does this look normal? Thanks!

Wind burn ??
Leaves are going down while looking healthy. The leaves on the top are growing normally.
It goes down more and more.
I dont understand if light is too close and she tries to flee it. Or she wants more light. Is it bothered by the fan ?
is it dying ?

Are these pre-flowers?My plant is still on an 18:6 schedule. This is my first plant. I noticed that these were growing more rapidly after topping. Are these pre-flowers.
I don’t know if it’s an auto flower seed. Here’s a pic of what I’m talking about.
Should I be preparing for flower stage?
