Good day,
I'm try outdoor grow for the first time, 4 plants in 20l pots.
About 14 days ago, I accidentally gave the plants fertilizer with PH 8.0 ("ph meter died") , after that i flush with PH 4.0. After 3 days i watered them with PH 6.0.
Today is 14 days since I last fertilizer and yesterday I found purple stems and a few dark spots on all 4 plants on the leaves ..
This afternoon there are dark spots on all the leaves and the leaves are curling upwards.
Would anyone please advise me?

Is that powdery mildew in the last picture?

Spraying in the sun? Helps if you give more info or it’s just a guessing game. If you’re in soil, your feed pH isn’t a big deal and not what is causing the problems.

I see phosphorus deficiency. You’re sure the white on the leaves doesn’t just wipe off like dust or powder?
