Help i have no clue whats wrong!!

I have checked pH it's 6.8 I have been on FF schedule and I have checked for spider mites and even sprayed the plant with homemade habanero pepper spray to eliminate any bugs that may have been there that I couldn't see.

3rd week into 12/12

Leaves get dark reddish brown spots on leaves, older leaves first, now newer leaves getting spots. spots turn into bigger patches and leaves die. Buds seem unaffected so far but may have stopped growing... Trichomes are present now but my buds are not getting any larger.

any suggestions?? (cheap ones and fast ones)

If no bugs..best guess is calcium.

i bought garden lime but it's way too late for that, what can i do to fix a Ca problem?

Use 1-2 tbs of Brer Rabbit blackstrap molasses/gallon, or get yourself some cal/mag

I cannot get to the brer rabbit molasses but I did a foliar feeding with a garden lime spray. do you think this will help?

Definitely nute deficiency.

calmag will work better... alhtough if it doesn't need mag ...

The leaves have big necrosis spots and are turning yellow and dying, started with fan leaves, spreading everywhere but hairs with trichomes. Hairs on the bottom buds are turning brown prematurely....is this nutrient burn? I flushed it and I want to fix it the buds look like they will end up nice if I can catch the problem now. I know you guys said nut deficiency but it's more grey and turning less green as a whole.

any updated pics?

the white residue is from foliar feeding with garden lime
