Fungus or deficiency?I have these gals growing outdoors and have a few leaves that look like this. Appeared after multiple heavy rain days. Applied nutrients yesterday so I still need to wait for the results. Is this a sign of fungus or deficiency?

What deficiency is this ?What is happening to my plant right now ?
I believe it is calcium deficiency also could be Manganese from the pictures. I did not add CalMag during the first weeks.
Usually Calcium deficiency shows after 4 weeks and during flower but not likely in soil.
Started around 6th week

I have only been using CalMag at half strength.. I normally go full.. So I suspect its Cal def.... But never seen it this color.. Different strains can show differently tho.. Help! Just on the 2 remaining fan leaves.. Not spreading to branches... Yet.

Overfed P and KUnfortunately i have overfed PK as thought the bottle said 7ml per L but instead was 0.7ml. Noticed tips of leaves the next day browning so checked the feed chart again and pretty much shit myself. Flushed all 3 plants for about 5 mins and now they seem ok hopefully.

Nutrient deficiency? If yes, what's the best course of action to salvage the situation?First time grower of 3 autos, at week 8, lower leaves started turning yellow, top leaves started to get smaller/develop brown spots 2 weeks ago. Is this a nutrient deficiency problem? Soil should have been fertilized for 3 months, but I'm thinking they burned through it.

K deficiency? Or something else?Not sure how to go about this deficiency. PH is solid at 6.5 so it’s not a ph issue. It seemed I had corrected the deficiency when it first appeared a few weeks ago, but now the brown spots seem to be spreading again. I think it might be K but not sure? Any ideas?

What is this brown spot?What is this brown spot? 18” from light. Just fed about 10 hours ago with dr.Earth 1-1-1 liquid solution watered in with 1/4 gallon of water. It is the only spot on whole plant. I know the temps are high. Wondering if it could be something else.

Leaf necrosisWhat's going on with mk Ultra? It gets Neem every 2-3 days, and I have tried to keep pH down to 6. This has been going on since I got the clone, and it continues to happen. The pink kush (last pic) has a few similar spots.
Lights are 50cm above.
