Nickname11123started grow question 4y ago
My biggest plant's leaves are turning brown while the rest of my plants are doing just fine, they are all given the same nutrients. Does anyone know what this browning is from and how I could fix it? I am only on week 3.

hard to say without more info but that looks like a slight pH fluctuation making the leaves react like that. Should be fine moving forward. hope this helps ! 🚀

Leaves browning like that is usually a sign she needs more cal mag if your growing under led lights this can tend to happen :) 👊

Fertilizer burn or something else?Hey fam. Plant seemed fine a few days ago besides a mag deficiency.
Decided to foliar spray cal mag at half strength a few times.
Now there are brown patches and leaves/stems are curling down like they’ve been overwatered.
Too much cal mag? Burn? Something else?
Thanks!

N or P deficiency?Need help to understand if this is P or N deficiency. It's on the lowest fan leaves, one is more pronounced than the other, and it's mostly on one side. Stems and veins look like they're giving hints of P def but from what I searched leaves look like it could be N def.
