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.

Leaves are turning yellow and dieing. Looks just like nitrogen deficiency. I'm in early flower
Losing a bunch of yellow leaves during early flower. I have WPM but it wouldn't progress like this would it? I think I may have just been underfeeding or my pH is off. What do you guys think?

Thoughts on flushing before harvest? I’ve been reading conflicting views on whether it is necessary or even harmful. My leaves are already showing deficiencies which leads me to believe there’s not even an excess of nutrients to get rid of?

Potassium deficiency?
Shes got about 2.5 weeks left, at first I thought the leaf discolouration was natural as harvest approaches but the necrosis has me worried. My guess is K deficiency. I was about to start flushing, will she make it to the finish line ok or should I attempt to fix this issue?

Yellow Colour
Some leaves have been turning yellow. Especially the lower ones. I thought it was a nitrogen deficiency as I didn't give the plant any nutrients till 2 weeks ago. Now I am feeding her with Biobizz nutrients according to their table. Should I be worried? Any recommendations?
