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

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).

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.

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?

Are CBD-Strains less nutrient-hungry?Hey Guys, i experienced that these strains like a lower EC/TDS. Every time i went over 1.2 EC (600ppm TDS) they showed signs of over-nutrition, like very dark green leaves and reddish brown leavetips. What are your thoughts on this? Are CBD-Strains less hungry on nutrients?

Insects, Mutation or related to my early nutrient burn ?Hey I noticed that one leave is looking like it has been eaten by something.. I checked every plant and also used yellow stickers, but can’t seem to find anything.
Is this related to insects or could it be something else ? (The plant had an early nutrient burn, but recovered)

Brown spots on top leaves - nutrients, light or something else?She went into flower, now stretching. Set light to 100%, added Bio-Bizz Top-Max and Bio-Bloom (1ml/L each).
3 days later brown spots appeared on top fan leaves, very few also on lower fan leaves.
I suspect this could be light burn or nutrient related.
Any ideas? Pls help
