Brown Spots mean calmag deficiency. Just add some and you’ll be alright. Hope it helps, good luck ☺️

Only single leaf, still cal/mag?
Anyone knows what causes a single leaf to show rust patterns, almost like cal/mag deficiency. Whole plant looks healthy except for this one leaf, literally. DWC, and I use tap water

Rust on leaves
Hi everyone. I've discovered rust spots on my leaves. I can't tell if it's fungal or nute burn, the rust doesn't seem to be coming off on my fingers which I think is a good sign? Does anyone have an idea of what it could be and whats the best 'next step' to take? Thanks IA ✌️

Which pests do this?
Exactly what pest does this kinda damage? I have my guess, but wanna get other growers' opinion on this type of yellowing of leaves and brown spots. 6 weeks into veg. It started very early on at bottom leaves, once I trimmed them this brown spots appeared on top growth.

When growing different strains in a RDWC system how do you balance plants with different nutrient needs. My amnesia auto ran into a major cal-mag issue and now is experiencing nitrogen toxicity, while my feminized Jack Herer's are largely unaffected. Thanks for the advice.

Nutrient deficiency? If yes, what's the best course of action to salvage the situation?
First time grower of 3 autos, at week 8, lower leaves started turning yellow, top leaves started to get smaller/develop brown spots 2 weeks ago. Is this a nutrient deficiency problem? Soil should have been fertilized for 3 months, but I'm thinking they burned through it.

Brown patches on leaves
Noticed these marks on the leaves of the plant I've had problems with. Any ideas what they could be? The other two are smelly amazing and the single plant is so sticky! I think it might be the cheesecake but I'm really not sure, I won't make the mistake of mixing them up again
