Calcium excess.. Check your local water report.. See how much calcium you have in your water to begin with.. Use cal-mag more sparingly..

Nutrient burnt leave removal question.
Should I remove all the burnt leaves? Worst ones are 25% burnt. Some just speckled throughout. Do the flowers still need exposure to the sun? Or will the leaves exposed to sunlight keep the buds growing? Can cutting the burnt leaves cause enough stress to hermie or stunt growth?

Not sure what's causing these purple leaves and leaves drying out. Plant overall seems unhealthy near the end of flowering, any suggestions appreciate
This Dos si dos Auto has been struggling over the last couple weeks with upper leaves turning purple and drying out/breaking apart. The buds also look strange to me but that may just be from my inexperience. I'm growing in organic soil and have dry amended twice, 18 days apart.

Spots on this one leaf
Can anyone provide some inside into what these spots on the leaf may be from? I know there was slight nute burn as multiple tips have indicated, but this is the only leaf I've seen with these spots. Thanks in advance!

Qué ha pasado?
It's the third time I've grown this strain and the third time it goes wrong for me. Literally, in 2 days it started with small rust spots like it was nutrient burn, I think, and today it spread a lot with those gray spots and the leaf deformation. Any ideas?

Serrated edges a sign of light stress?
I think the LEDs are too intense. Do the serrated edges of the leaf tipping up mean they are being stressed by the light? Because I don't have heat issues. PPFD Around 780-980.
