Keep an eye on your pH... pH fluctuations can cause brown spots between the veins. If not brown but more yellow its magnesium. can also be caused by pH fluctuations but believe from your explanation its the former. Make sure your pH is between 6-6.5 for soil and 5.7-6.2 for coco. good luck

Can't really see with that light color but I'll give it a try:
-Check under the leaves for bugs. I had spider mites doing those marks on my plants before but might be something else.
-What nutes you're using? If not bugs I would say calcium deficiency? Is it possible? Without more info about your grow is really hard to guess.
-Also when a plant is overwatered for too long or has "wet feet" similar brown spots can appear and be mistaken for calcium deficiency or other deficiencies.

Weed doctors to the rescueDay 44, fb auto, my happy girl developed those dark spots at the top... Is this a Calmag deficiency? Although I'm giving her calmag every feeding. I think there are also first burnt tips. I'm about to water her tonight, what should or should not give her? Thanks for your inputs🙏

Nutrition deficiency or nute solution on leaves during watering?Hi Growmies,during my monitoring routine I found some brown spots on the leaves. Not many but on some leaves the brown spots have become transparent and I can see through the leaves. Any ideas what could have caused the brown spots? Perhaps not enough CalMag? Rest looks healthy.

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?

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 cycle
