Brown spot on leaves
sashagrowstarted grow question 6y ago
I'm experincing a bad situation. Leaves are becoming brown in the margins and I can't understant exactly the cause. Probably there are more causes, some phosphorus deficiency caused by low temperature but I'm not sure that's the only diagnosis.
Someone could help me?

Your showing magnesium deficiency for sure. I would suggest testing run off ph and making sure soil ph is in range. If not that is cause to all nutrition problems . Good luck and happy growing 🌲🌲🌲👊

Calmag and micronutrient deficiency due to a lockout caused by too much P and K. Bud development is largely done and she requires less nutes in this last week or two. This means it's much easier to burn. Leaves will start yellowing around now anyway so I wouldn't worry too much about the yellowing.

Saw this first day of 12/12Pretty sure this is just where I got nutrient solution on my plant yesterday when watering unless it's something else? I pulled these leaves off 1 plant when lights came on this morning. Every Plant looks 💯 great besides these 3 leaves, all from 1 plant rest of plant is great.

Possibly Potassium Deficient? Based on ALL the pics I could find, but not sure.I noticed these brown splotches and leaf edges on one area bud and pistils of my Orange Sherbet last night. Based on what I can find online, this might be potassium deficiency?
This is mostly on one spot near darkest edge when tent closed. Thanks!

Bruciatura da luce o fertilizzante ? (Dwc)HELP! I would like to solve and find a valid explanation for these leaves that are burning, mainly on the main stem, which is the most exposed to light." I have also added a dose of nutrients since it is the last week of bloom. Does anyone have any idea💡? Thank you
