Are #1's leaves showing burn-like signs?
BerrySweetHighanswered grow question 5 months ago
Yes it is from the heat but it will recover. Try to keep them cool and turn the lights of during the hottest time of the day instead at night. This way you also keep a more stable climate for the plant.

9 times out of 10 with seedlings it's a watering issue. You can tell by the crinkled leaves as well that your environment isn't quite right so I would definitely keep your VPD in line as well as getting a moisture meter if over watering or under watering becomes an issue.
Hope this helps.

The bit of lead warping on the first set of true leaves looks like it could have been caused by overwatering. Easy to do when the plants are young as their root mass is not that big yet.
If the temps are high remember to keep the air movement up. Lower is better but it can handle it easily enough.
RH of 55% at night is perfect I would not change it.
Good Luck!

Can't see anything that would cause any concern for me.
No plant will ever have 100% perfect leaves, 100% of the time.
32 degrees and 55RH are not going to be a problem for cannabis.
Cannabis is a tough and resilient plant, not a dainty "princess perfect" exotic orchid.

Yep thats typical for heat damage.
Just look and that shrunk on bigger leaf...
Thats hurt by too high temp.
Optimal for grow 24-26 max 30 (not good imo).
32 for hour can make such damage.
U need to lower that ASAP.
Humidif. For 3/4 first weeks optimal 45-60/65.%

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).

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.

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

Plant starting to yellow too fastThe crystal meth has started going yellow very fast. The buds still have at least 2 weeks of growth needed to fatten out and pack the trichomes with thc.. I know it is normal to start dying but isn't this a bit early? Should I let her keep going as long as sugar leaves are alive?
