Are edges burnt and why if so?
ultra_violetstarted grow question 9 hours ago
The highest and main cola has a couple of leaves with such strangely-coloured tips and edges. Is it a sign of light or nutrient burn? The weird thing is that only one cola has it so far and just a few leaves on it, not even all of them. She is on her 4th week of flowering.

More than one thing can cause that, so you're best seeing how it progresses.
If mindflowers is right, that's either genetics cooler temperatures (68F or below) occurring at some point in daily cycle.
If it's definitely red/purple coloring, then it's just genetics / cool temps. They look black to me, but photos are deceiving.

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! :)

Nutrient lockout, ph imbalance or nutrient burn?Unfortunately I don't have a ph meter, so my best guess is one or more of these problems: nutrient lockout, ph imbalance or nutrient burn.
The first 3 photos are from an Auto Northern Light and the last 2 are from an Auto Jack Herer.

Progressive yellowing on older fan leaves ~F14-F35Hi, past two weeks or so I've been noticing progressive chlorosis and eventually some necrosis starting from the edges of the leaves and working inwards.
Photos of this can be found in Week 18 Flower denoted by "For grow question #x 12/1"
Humidity low, could be related?

Yellowing, burnt tips and edgesHello fellow growers I noticed this happening rapidly after I top dressed. What kind of deficiency is this? Is this nutrient burn as well as a deficiency? Solely a Ph problem?. So far I’ve come up with maybe potassium deficiency and improper Ph when watering? Please help

What to do? Leaves are getting worse.Had some light strain earlier on, but now im leaning toward a deficiency. Been feeding on a low-dose flora series schedule with clean ph water for every other feed. Just had clean water yesterday and nutes 3 days before. Dry out between feeds. Nitrogen? Calmag? Other?

If anyone can help me identify the cause of these burnt tips it would be a great help!
For info:
Amnesia haze week 9-10
Ph runoff is 6.4
I’ve had problems with calmag deficiency before so it could be that
Using biobizz light mix and biobizz nutes
Anything helps!

Leaves burnHi! Is this nutes burn? Damage is on the upper/middle part of the canopy on very few leaves, but many more have black tips.
I’m puzzled because during veg I was feeding the plant higher ppm than now and never had a problem!
