This looks like it could be ph lockout . Try flushing your plant and see how she does

Hi! Check on "tobacco mosaic virus". The yellowish stains could be signs of it. Good luck!! :)

Kind of looks like very weird Potassium excess. Could be a form of PH lockout.

I don't have a PH meter, just some test strips. Can anyone recommend an inexpensive meter I can get in the UK? There's a bit of yellowing on some leaves (see my diary entry on week 8) Buds seem to be developing a bit slow Should I switch from 24 hr to 20/4 or 18/6 ?

Yellow leaf tips and edges
Hi I've got a problem that I've seen from the start of my grow and it's getting worse on older leaves now - zoom in edges and tips are turning yellow. I thought it was magnesium so I've dosed with Calmag but it's not improved - I'm Ph6.5 - any ideas?

Nutrient Burn, Leaf Septoria, Nutrient Deficiency? Or something else?
I have been having issues with the Purple Haze. I've tried adjusting the Temperatures, adding additional Cal-Mag, changing lumen intensity etc. I believe this may be nutrient burn? Added an old image of leaf before mainlining, the plant is 1 week old after mainlining was done.

Yellowing leaves
Hi Growmies, im in week 7 of my flowering cycle, my leaves have started yellowing between the veins before turning brown and dying from the tip inwards. Is this a calcium deficiency? Or is it natural dying from the end of flowering cycle or something else? Please advise thanks ✌️

Yellowing spots and holes in fan leaves
Is this leaf septoria? The bottom leaves are mostly infected. It has been raining heavily and some fan leaves were touching the bark on the pot. Thanks for any help!

Yellowing Too Fast Or Natural?
I'm roughly 2-3 weeks into flower. Over the last week, I've noticed more yellow leaves than normal. Majority are bigger, older fan leaves but some are moving up the plants. New growths are a nice green and buds look healthy. Am I under feeding or overreacting?

Burnt edges / yellowing
What are all these burnt edges from? One of the burnt leaves is from the perimeter, so I'm not sure how it could be receiving enough light to burn. I also have a small amount of yellowing towards the bottom. That's normal during flowering if the low-light leaves die, right? Thx
