Brown dots on fans
Burmeseanswered grow question 3 years ago
Hi there, I think you have nutrient burn and calcium lock out .As you are using a decent amount of nutrient, there is small possibility for deficiency. Have you been checking your run off pH and ppm regularly?If not, check both run off pH and ppm(EC).Maintain your soil pH around 6.5 for both in and out.Also check ppm(EC) whether it is too much different or higher than what's in.Try to avoid Nitrogen rich nutrient during this late flowering stage.Good luck and happy growing... ✌️

Yes it’s a Calcium deficiency, probably curbed by an excessive amount of ammonium, potassium, magnesium and/or sodium in the root environment.
Control the EC level of the soil by checking the drain and readjust following plants needs.

At this late stage of flowering, I wouldn't worry about it, but I would be cutting back on the nutrients, especially nitrogen, the leaves are super green and with burning starting to show.

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

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)

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?

Stresst es Pflanzen sehr, wechseln von LED zu SonneIch wollte mal fragen ob jemand Erfahrungen gemacht hat seine Pflanzen bei schönem Wetter raus zu stellen und bei normalem ins Zelt unter LED. Gibt es da negative oder positive Erfahrungen von euch? Ich habe ca.65k lumen unter der LED und die Sonne bringt es so auf 120k lumen...

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?

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).
