A few small changes can bring it on more or earlier or both, such as brighter lights or a change in the VPD.

Hopefully you’re right. Its defiantly happened before , but I think it’s more than just fall colours and the leaves dying off
Just trying to up my game as always

[Gingerbeard]

Actually, the leaves are turning off and the buds are soaking up all the nutes. Just keep with the bloom mix.
You've been growing for a while. This has never happened?

[Smallgrow]

Ya it’s a drag cause you know it’s taking away from the finish product so close to the end

As a living soil grower I don’t really PH.
I do from time to time check the soil ph and it’s always 6.5-6,8 so pretty bang on
Yes calcium was a thought I’ve been adding more crab meal to my mix maybe I need more or a different source

[Bluey]

Agree with roots. Are you checking pH of inputs?

Mid-late stage flowering deficiency. Annoying but normal.

Looks like some sort of deficiency. Calcium?

Hi all
looking for some input on what’s troubling my girls
the two bigger plants have a lot of browning. I’m leaning toward overwatering. I water using Blumat auto watering. I’m not planning to do anything except get to harvest but I like to know what the community thinks for next run.

They are about 4-5 weeks into flower at the time of pics they are in Organic living soil in 7g pots.
I generally amend my soil before my grow starts, and at the beginning of flower I amend again with a bloom mixture, which is what I did this time
temp 75-77f day , 70-72 night 45-50% RH

Im running about 650-750 PPFD from my Photontek LED. I do struggle with light burn generally as I grow “sativas” and there hard to keep short enough.

any input is appreciated, thx

No tip browning. But I've been in flowering for ten days. I usually start boost at the beginning of week 4. But maybe I should start at beginning of week 3. Just a small dose.

You could try this but I don't know about the back of the leaf. Yours looks extremely minor. Do you have browning tips?

What is this? I have no issues anywhere from what I can see. Just one leaf every so often that this happens to it happens every cycle but i dont get any other symptoms or problems. I've suspected that it's damaged caused by a wet patch when leaves have touched and after it's dried. Or is it something else?

Hi static

Isn't the mottled look a symptom of overwatering?

Also check your RH and temps, and get it into a decent pot.

Hi all! Newbie grower here!
I have a few plants in veg right now, all different strains, others are fine but this one is struggling… I was going to lean towards it needing a 4-4-4 feeding but figured I should ask first before jumping to the more nutes … I don’t have any more photos at the moment sorry ensive:
