Hello friend, yes you have a calmag deficiency, they need a great amount of it when they’re in in veg phase. You have a nice plant there, good luck! 😊

Spots on plant? Is she sick and how can I help her?She has some spots and I'm worried for her. This plant is the only one in my tent like this, none of my others have spots. And I did transplant her to a 1 gallon pot, but she needed it. Her roots were growing out of the solo cup. Does anyone have any ideas what's wrong with her?

leaves dry and curling up Gelato canopy leaves continue to dry and canoeing up. I've backed off the lights, changed the air circulation, and gave only water in the last week, but the situation is just getting worse. Canopy buds are not growing and trichomes production is much higher in the lower branches

Magnesium deficiency? How to cure it?Is this a sign of magnesium deficiency (my other plant has similar spots)? If so, I've read online (on the Canna nutes website) that I should spray the leaves with Epsom Salt (2% solution): is this correct? Any other suggestions? Thanks in advance

Slight damage to one of cotyledons If you look at this picture you can see slight damage to one of the cotyledons, I don't think it's due to light as the damage is on the bottom side, maybe I watered it to much. Should I worry?

Brown Spots on Leafs Thanks guys, must be the break as it flowered early too... I also noticed some brown spots on both plants, some leafs . Worried it's mold but it wipes off with moisture and I've been misting with molasses water. Staining from too much molasses in the mister maybe?
