yellow/copper appearance in some leaves after first run off watering
hi! after the first run off watering the girls seemed alright, sturdy and firm but some of the leaves (one leaf, 3 plants currently) experienced copper/yellow/orange tints . this is only on old leaves so looks like mobile nutrients. could this be cal-mag issues?

Scared of bud rot
So my last harvest last week had bud rot and I noticed my Royal jack has a lot of yellow leaves but I think she still needs at least one more week to grow. Could this be bud rot even if I don't see any other signs? Should I do an early harvest just to be safe?

Yellowing of top fan leaves
What is causing yellowing of the top fan leaves? Started to happen to a plant that I broke by accident during LST. However around the same time I upped to 2ml/l and moved the light a little closer. My ph has also been high (fine now). No idea which one could be the culprit

What is happening to my plants?
I had them in the terrace outdoors. Temperatures sometimes reach 40C. Lately more and more yellow leaves in the ABC have been showing up. In the other normal leafed plants crispy dried and brown leaves are showing. Now the ABC also is showing some dry leaves and yellow as well.

Is this light burn?
Is this light burn? If not what is it? It's under a Phillips 13w household led 2700k bulb, it's not the only affected area but it's the most affected and the closest to the bulb. I plan to add more but don't want the issue to accelerate. Thanks in advance!
