hi there Habosabin, that's micronutrient deficiency, you're adding silica which is basically optional but you're forgetting calmag which is absolutely necessary in soiless grows. Just add calmag asap . Hope this helps ! 🚀

Hey guys I'm puzzled i took one picture of a leave from my Royal Ak 47 Auto. As you can see this is not a nice green healthy leaf (many others are like this). What's the issue? Is it worth treatinbg this late in the growing stage? Love to hear your opinion :). Cedji

Orange/rust spots on leaves Throughout the life of this grow I've seen rust and orange spots on some of the fan leaves. I can't seem to figure out or pinpoint the source of this. I think the plants are in good health overall, I do have a lot of fungual gnats that I'm trying to mitigate

Can anyone help me identify the cause of the rust-colored spots on a couple of these lower leaves? I am guessing some kind of nutrient burn.

What's going on with my clones? Do not have much information to add. VPD is not terribly off, DLI around 25.What's going on with these clones? Not sure what it could be. They could possibly be rootbound. They should have been transplanted a few weeks ago but I did not have the space.

Weird color and strains on leaves Today my plants got something weird on their leaves. Some stains appeared on older leaves, and the new ones have a strange color, it looks like they are painted. More or less the same on another plant, some edges on new leaves look burned and weird color and shape on new leaves
