Looks more PH related in my opinion, although the rest of the plant is largely healthy- and it's hard to tell under the blurple light. Do you check your runoff PH? Input PH?

yellow/dark discolouring of leaves late into flower
Noticed this on about 5 leaves, some more affected than others. The plant is towards the end of the flowering, with about 3 weeks left, better to ignore it now or try to do something ? perhaps leaf Septoria, already increased air flow and decreased humidity

Желтеют листья.
Всем привет! Выращиваю первый раз, сорт Auto Opium, растению месяц, нижние листья начали желтеть и вянуть, это связанно с переходом на цветение? И за какое время растение будет готово к харвесту? Заранее всем спасибо за ответы😄💚

Yellow leaves working out towards tips
Yellowing of lower leaves, from the stem working towards the tips. It’s been hot and they’ve been home alone for 5 days with just one water on the 3rd day. They had a small amount of bloom just before I left! During veg they were on fish mix, but not very much (1/2 dose).

Plant issues... How long to harvest?
Could someone please look at my (only) diary and give me an estimate on when harvest might be? I have microscope pictures up . I think I see cloudy trichomes with the possibility of a few amber. Maybe ready now? Not sure but hope to harvest before plant gets much worse. Thanks!

Anyone have any ideas what could be causing the yellowing in the leaves of my Pheno 1? I think iron def - its the top new growth & is working from the inside of the leaves towards tips. Tested feedings of liquid seaweed & water to pH 6.2 but not run off. May be dry am. nute

Leaf discolouration. Nutrient deficiency?
Leaves are discoloured and clawed. Started about a week ago with yellowing of tips and clawing at top of the plants. Now lots of leaves are slowly changing colour. Thought it was nitrogen toxicity but my runoff is 330ppm. Are they deficient in nutrients?

Little seedling having a hard timr
So guys; I'm worried about this seedling. She's having trouble on keeping up with her sisters. I noticed a yelow color on their tinny tips 🤔 Cotiledons got brown pretty quickly too. She took longer to "open" the cotiledons after popping from the soil. Should I do something?? 🙏

She has yellowing and dying leaves issue for a while now. I was giving more nutes lately to combat the issue. Now burnt tips say it is to many nutes. So I decided yesterday that I should water with a bit of calmag before next feeding at beggining of the week.
