Stains on Leaves
Ch33cHanswered grow question 4 years ago
How is your airflow in your growspace? I had this quite often years ago and when i improved my ventillation and airflow inside the room it went away and never returned.
If its not that then you have maybe either spilled nutrient on the leaves or its the sign of the start of a lockout.
But really could be the circulation in your tent/room. Its the bottom leaves and wouldnt worry to much but if it starts to spread you'll want to get on top of it.
Good luck man.

Wet shiny spots on leaves.I find occasionally such wet shiny spots on leaves. Any idea what the root cause and how to fix it?
They are not sticky although look like.
I cannot say whether they smell because smell of the leaf is too strong 😶
I can rub them off with the thumb with no sign

3 days in, only cotydelons with no sign of the first true leaves. Have you seen this and has it recovered?This plant was stunted at the start after he couldn't get his hat off, but now looks pretty healthy however it's been 3 days of just cotydelons and absolutely no sign of the first true leaves. Have you had this before and did it recover to eventually grow true leaves?

First Grow 4 weeks into Veg - Let my humidity get too high for 1 night. Need help with mold/septoria/?Last 3 days I've pruned diseased leaves every morning, foliar sprayed peroxide leaves & topsoil, & added some to watering solution. Is only affecting one plant in tent. Humidity no longer issue (was waiting 4 inline fan). If I keep pulling off leaves it's going to die anyway.

Big difference in first true leaves' sizeBig difference in first true leaves' size
Its almost day 5 after emergence. Is this normal? Should I be concerned?
ALSO: It's still a seedling but, I maybe think the cup in which i'm growing it in is too small, or rather I put too little soil (9cm diameter , 4cm tall dirt).

Strange Brown Spots Forming On Top Fan LeavesJust starting week 5 and currently in preflower. I'm starting to get some strange brown spots on some of the top fan leaves nothing yet on any of the lower leaves. I rubbed my finger over the top to check if it was rust fungus but nothing came off. Any suggestions? appreciate it

White lumps on fan leaves?I have some pics of white lumps on the leaves does anybody know what these are? I was worried it was mold but I’m not sure, it is not fuzzy and doesn’t seem to wipe off at all?
It seems to be part of the leaf structure? I mostly see it on older darker leaves, not trichomes?

Starting-to-Cook Deficiency?I can’t seem to find issue. Look close at brown leaf spots. Rock solid variables with a tweak in the diet in week 7. Was the light cooking the life out of the canopy for last two weeks? Light was 8” and 1500-2000 PPFD before I yanked the top shelf out 3 days ago for distance.
