That looks like a problem by a low ph, raise that to 5.9 even 6 for a feed and see if that improves. I am pretty sure about that too my friend👍

Hi guys my special queen has got brown leaves and they look like they're getting worse. It pretty close to harvest so I don't want it to die at this stage. It's my first grow so any tips or advice is appreciated. Thanks

Deficiency?
I laid off the nutrients last week after some concern that I was overfeeding, but I think that resulted in a deficiency. (Some of the darker colors might be related to the strain? 🤔) The third picture was taken 12 hours prior to the first two, so it progressed quickly overnight

Sudden brown on leaves
These brown patches appeared in the last 24 hours. It rained heavily during that time. Any ideas what the issue is or what to do to treat it and/or avoid spreading?

What nutrient deficiency is this?
What nutrient deficiency is this? Or is it nutrient burn? I'm watering with 5.5 PH using half strength Nutes, Root booster & Calmag. I don't think it relates to spiders mites since I can't see any with my 30x magnifier. Thank you so much in advance.

Aeroponics system; fan leaves start browning on edge in 2nd week of bloom.
Aeroponics system that my fan leaves start browning on edge in 2nd week of bloom every time (about 7 grows in journey). Is this normal? Should i be concerned and adjust nutes at all? Or just selective trim any of the more "crispy" ones? Photo is 2nd-3rd week into bloom.

I am seeing an issue with the lower fan leaves and it seems to be progressing upwards. The leaves are yellowing and also seem to be turning brownish. I added CalMag into my last feeding but beyond that not sure what I should consider, info/advice is appreciated. See last pic wk5.

Browning leaves?
What's up with these fan leaves? I'm starting to notice some light brown hues in a couple, mostly closer to the bottom of the plant. Anything to worry about?

Late Flowering Stage Deficiency or Nutrient Burn
I'm not sure if this is nutrient burn or some sort of deficiency. Burnt tips were from possible previous nutrient burn, but now I'm seeing Brown spots and some discoloration. Please check my week to see full details.

No logro descifrar cómo arreglarlo - auto en DWC
4 and a half weeks since the start, pH 6.0, ppm 600, includes base nutrients + calmag + silicon + trichoderma. Same problem throughout the entire vegetation, in the 4th week I included calmag and more fertilizers and it seemed to improve but now it's declining again. Over-fertilization? Deficiency?
