The only K I see here : you shoot a ~2000K scene with the white balance of your camera set to ~5000K. :3 Leaves colors will help to diagnostic. ;)

Problem with plants in the 3rd week of vegetation.
I'm posting again because I accidentally marked it as resolved. I was using BioBizz CalMag from the beginning, but when I switched to Advanced Nutrients, I stopped because Ph Perfect Sensi Coco Grow A and B already contain CalMag.

Dry brittle leaves
Discoloured older leaves curling up at the edges and turning dry and brittle. I think my problem is over or under watering. I've been very careful to avoid overwatering so I'm leaning towards the latter but what I've read online suggests dry/brittle means overwatering. Thoughts?

Leaves yellowing and burning mid flower
Air exchange, pH, nutes, and water should be good. Could my 230 watt on 100% be too much for her? Does she need more humidity? What causes crispy leaves?

2 Yellowing Fan Leaves
I have 2 large fan leaves from the main cola turning yellow and 1 almost looks crisp or burnt on the edges. It is only 2 of the leaves and by my reckoning, they are 2 of the oldest leaves on the plant. From research, it could be the bump in nutes or water issue. Any ideas?

problems with low leaves
in the lower part of the plant some leaves are yellowing, others are drying out and even detaching. can it be due to the fact that since flushing (a week ago) I have not given anything to the plant anymore? I hope this does not compromise flowering

Discoloration and burnt edges on leaves
Can someone please help me diagnose this problem? At first I thought it was root dry spots from the drip watering system but it’s gotten worse. The bottom leaves are yellowing and the edges are burnt with a hole in one of the leaves. Anything helps, thanks!

2 autos with crispy feeling sad looking leaves, how can I help them? (more info in diary pl & crit)
2 of my autos have been growing leaves that feel crispy and look deformed. I have been watering when the top 5 cm of the soil dries, but I fear maybe I fed them too much nutrients. The temp has also been on the high side (30C 80F). What could be wrong and what can I do for them?

Leaves turning brown/purple
The leaves on one plant started to turn a little pale, and with brown/purple spots. And on the other plant it starts to turn more yellow, probably Nitrogen deficiency for this one. What do you guys think ?
