here is some info, maybe this can help https://www.marijuana-seeds.nl/blog/calcium-deficiency-in-marijuana

If growing in soil ph should be 6.5-6.8. If growing soiless ph 6.2-6.3. If you check runoff ph you will be able to get an idea of what to set your feed ph to, in order to get your ph in check. If your ph is good, then you can add cal-mag to your feedings if you aren't already, about 1tsp per gallon. Hope this helps. Happy growing.

Hey,
That is most likely calcium deficiency, usually caused by low ph, in soil.
Cheers,

Browning leavesMy leaves are showing some brown spots 5 days post transplant. I also increased my light from 30% intensity to 80% intensity. I have them 18” away currently. Am I showing signs of light burn? I have since turned the light back down to 50% and I am not on a 18/6 cycleWeek 1

Bud rot? Mold?My plant is a bit problematic ("quick one" Auto from RQS, outdoor balcony grow).
I'm a bit worried that I have to throw it out, therefore I would like to ask for your expert opinion. :)
1. Is the "brown stuff" on the top bud "bud-rot"?
2. Are the "more intense white spots" mold?Buds. Other

could this be due to the PH being too low?I watered 3 days ago with PH 6.3 Ruoff was 6.0
today watered with PH 6.6 runoff was 6.1
Can the brown spots come from the wrong PH ?

Brown/yellow/purple leaves inThis started out as brown spots on big fan leaves and has turned into what you see on the pictures. I've been ignoring the discoloration until I was greeted by some wilted, dead leaves on plant #2 today.
I'm not worried at this point, just really want to know what's happeninga month ago
