Hi!
Pura vida!
Your Grow look fantastic duddyđ. Im 100% this not a plague because already have it before and for this flowering state and the damage are not the same of mytes,
produce in your leaves if you had a myte infestation would be covered in spider weeb in less the one week...
You have a (Mn) Manganese deficiencie/toxicity already rare. I saw before in a video of a youtube channel called Perfect Gardens, and you can checkout your same damage and decolorations in (Septoria, Botrytis, Manganese, or Calcium (Pt 2), 2021)" and according to... (Characterization of Nutrient Disorders of Cannabis Sativa) Your new leaves look liked a avancend Toxicity of Mn shown in shown in his studio. I left links in References.
Good Luck, and i hope you harvest soon and massive đđđ

Not thrips ... the overwhelming consensus is SPIDER MITES...

Hey my friend... the answer came back REALLY quickly from a group of growers I'm hooked up with on FB.... you've got a bad infestation of either spider mites or thrips..... Get yourself some Dr. Zymes for next grow (since you say it happens every grow!!)....

Man, I've never seen anything like that, my friend! I don't think it's calcium at all - leaves would be more yellow and there would be brown spots .... I agree with you that you probably shouldn't worry about it since you're so close to harvest (amazing looking buds, btw!) .. but now you've got my interest picqued and I'm going to try to figure this one out... If YOU find out, send me a msg telling me!
Good luck!!

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).

Sagging leavesI have (2) 9 day old purple punch auto seedlings. They both have sagging leaves and were fine yesterday when I watered them. I think itâs because I have them in 2â peat pots inside solo cups. They get plenty of natural sun. They werenât watered for 3 days before that.

Bugs creating holes in leafs?Does anyone know what this could be from and the best course of action? I can't find any visible bugs on topside or underside of the leafs. Have been putting her outside for a few hours each day for the last week. Nute burn is from hot soil from bottom of the pot she grew into..

Brown Spots on LeafsThanks guys, must be the break as it flowered early too... I also noticed some brown spots on both plants, some leafs . Worried it's mold but it wipes off with moisture and I've been misting with molasses water. Staining from too much molasses in the mister maybe?

Possible N ToxicityI believe I have a N toxicity issue on my hands. Leaves are a dark evergreen color, and I'm noticing some leaves are curling left or right. I've experienced the full out clawing action a while back but never like this. Is anyone able to confirm? How do they look overall?Thank U!
