Hi!
Pura vida!
Your Grow look fantastic duddy😉. 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 👌👊😁

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!!

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?

Stains on the plantHey guys,
first of all, thank you for taking the time to read this. I started growing my first canopy and since I am little excited, I started before everything I ordered arrived. For that reason, I am still using the soil I used while planting the seed. Did I fuck up already?

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

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.
