Looks like natural leave colours to me, don’t worry too much just keep an eye on it. Leaves are prone to develop mutations

Just to confirm, this looks like nute burn, doesn't it?
Burnt edges, tips curled up, canoeing. I've been having trouble balancing airflow and heat in such a small tent, and as a result the tent is on average about 28 degrees celcius daytime and the plants still get a lot of wind. Looking for whatever advice you can give! :)

Rust/dead spots
This girl, was overall stressed out from the beginning. Lights, overwatering, ph , wind burn, you name it. Either way all of the plants have long recovered. Still stunted tho. Plants have only received one 1/4 dose of veg nutes. Are the spots from lack of P and K?

Light stress?? Wilting leaves, shrivelled and burnt edges. See pics in last week.
Any idea what’s going on? Leaves are shriveled and wilting, as well as some burning at the edges? I’m guessing this is from light burn/stress as I’ve only watered and used very very little nuts so far. Lights were at 22 but now at 30. Temp is 24 w lights on, 55 humidity. C pics.

Root rot or pH imbalance?
This blueberry muffin (f) plant was doing well until last week when it started deteriorating. Its grown on a mix of cocopeat, vermicompost, perlite mix and fed on compost tea and cal-mag mix. I might put it down eventually but I checked the pH and it was 5!

Nutrient burn?
The leaves on my two plants are starting to show signs of burning. Is this nutrient burn? I have no added nutrients yet but I am using Happy Frog soil. I’ve raised my lights from 24 to 28” in case it’s light burn. What are your thoughts and recommendations?

Potassium deficiency?
Shes got about 2.5 weeks left, at first I thought the leaf discolouration was natural as harvest approaches but the necrosis has me worried. My guess is K deficiency. I was about to start flushing, will she make it to the finish line ok or should I attempt to fix this issue?

Leaf Edges discoloured
I stopped nutrients a week ago. The soil is SoHum living soil though. Only gave CALMAG and BioBloom as i noticed a likely N deficiency. Today i noticed the tips are discoloured. Should i be concerned? Today they’ve been in flower for 7 weeks. Ill give them roughly 2 more weeks.
