I would do a slurry test of your runoff water ph and ec levels. Looks to me like your ph is a little out with the look of some of the leaves. Adding a little cal/mg is never a bad thing, but you ph creeping up is.

Ph somsagt nogle gange hvis du har gødet og ramt bladene så spray med ren vand efter kun på bladene (aldrig på blomsterne)
Men tror nu mere det m ph:)
Godt grow

I see in your diary that you just added some cal-mag and you did good because this is indeed a calcium deficiency. But you've got another problem, you need to measure and adjust pH. You can use a biological pH adjuster like the one from Biobizz. And a cheap pH measuring tool would be enough. Make sure that your pH will stay within the right range between 6-7 to prevent deficiencies and nutrient lockouts.

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?a year ago

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.Leaves. Other

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).Leaves. Other

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)Leaves. Other

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 help9 months ago

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?Leaves. Other
