Brown spots on some leaves!
MadeInGermanyanswered grow question 5y ago
Hi your Ph and Ec are perfect, your plants look great 😍👏🏻. Look at the wise spots and holes with a microscope to see if you can find any animals?

Hi!
To me it looks like acidic water damage. I spillled some phosphoric acid on one leaf and turned kinda same.
My guess is that maybe you spilled nutrient water or something to those leaves. Watch if they spread or you start to see more cos it might be something else too

New brown spotsThese brown spots came out of nowhere, all over the plant. Had no issues with spots up to now. She’s 4-5 weeks into flower, recently started canna terra Flores every other feed. Also added some seabird guano recently. Please let me know what you think and thanks

Strange GrowthDoes anyone have any tips or explanations on Kate and Randall's weird growth patterns throughout the grow so far? Kate has always had short fat stubby leaves. Randall has not grown a new fan leaf in what feels like a month. I think it was root bound before I repotted.

Garden visitor eating my fan leaves.This is my second grow (outdoors) and I need some advice. Saw some holes on the SSH fan leaves. When I flipped one of them over, I found a visitor that I think is a Spider Mite. The grow is looking good but I want to avoid any problems. How do I get rid of them?

Manchas en las hojasHola amigos! Estoy teniendo algunos problemas en las hojas y aunque creo que con Calmag se solucionarán me gustaría oir vuestras opiniones. He notado también que algunas puntas de las hojas se curvan hacia abajo, ¿cuánto creen que me está afectando la temperatura de entre 27-30º?

Do I have pests?I’m growing a Zkittlez alongside an OG and Gelato. Some strange holes appeared on the Zkittlez 4 days ago. I don’t see any evidence of pests other than the holes. Does anyone recognize this or have any suggestions for fixing the problem? No damage on the other plants. Thank you.

Exaggerated texture and discoloured leavesHi Guys
I’ve notice that some of my leaves are extremely rough/overly textured with slight discolouration, almost looks highlighted or over exposed in colour with some light yellow/ brownish visible. The plant looks alert just a bit odd. It’s only the 1 plant of 2

Heat stress? Light stress? Nute burn?Hi y’all
Since my girl started to flower the top leaves near bud sites have this weird cupping downwards look. I doubt it might be a nute burn since I already gave her a good flush.
I think the heat might be the main issue (86-87degrees during day).
What do u think?
