Discoloration bud leaves
Anybody know what this discoloration is? Humidity was a bit too high so I'm hoping not some type of mold. The affected buds did get quite a lot of wind and light, so it might be light- or windburn? Any help appreciated!

Help! Lower fan leaves drying out slowly at the tips and edges. Doesn't look like nitrogen deficiency to me, but please prove me wrong!
10 days ago the lower set of leaves started drying out (they get brown not yellow). They don't receive light, but now it's already started showing on the third set of leaves. Does it look like nitrogen deficiency or can it be something else? Just gave it full strength nutes.

Browning of leaves, heat burn or pests?
Plants are showing signs of browning, and other weirds leaf markings, kind of grey-ish not too pronounced. It's been very hot and sunny here for 5 days, temps reaching above 37°. I left them in the sun during this period, is it heat stress? Otherwise growing nicely.

Should I cut these off ?
leaves are no longer crispy and dry but are still rapidly changing colour, not sure if I should cut them off or let them fall off themselves ? if I cut them off would it be beneficial ? not sure if the plants still putting in energy to keep these leaves on the plant or not ?

Brown spots
What is this? It's affecting newer growth, first or second set of fan leaves off thee top of the colas. Also, this drooping, is this stress from the light? This is the center of my tent, and would appear to only affect tallest colas of this plant.

Orange/Yellow spots on leaves
Today I noticed that one of my plants has an orange/yellow sign on a couple of leaves (see photo with the tag "28/02"). The spots are small and the leaves seem to be healthy (so far). What the problem could be?

Leaves turn brown all of a sudden
What could these brown parts mean? They show up randomly, also on lower leaves, so couldn’t be the light being too close? Thanks!

Hello fellow experienced growers, is what I see on this leaf, combined with a reddening of leaf and main stems really signs of a CalMag deficency? Or do I have another problem? And is 1 ml CalMag Agent enough to counter it? Dont wanna risk anything so close to the goal...
