Browning leaves sections of leaf surface discoloured
Day 18 leaf worries, browning areas, slightly metallic shine. I think from reading it might possibly be a phosphorus deficiency but I’m not certain so though I’d ask for advice. Thank you for your time and all answers are appreciated. Have a great day!

What's causing my brown crispy leaves!?
Over the past week my plants have taken a turn for the worse. Many leaves went from yellowing to browning to completely crispy! Other leaves have brown spots on them and some of the stems are purple.

Condensation, CalMag, Nute Splash?
Twice between heavy defoliations the were leaves were so jammed together some leaves would get wet from contact with other leaves. It's the only leaf on the whole plant like this - as of now. Seems like Calmag? Product of sweating? Nute splash? (week 7 photos)

Yellow leaves - moby dick
The olders leaves started to die and to turn this yellow-brown color. I thought it could be the temperature (I am about to receive my temperature hydrometer to measure that), or over/less watering, or nutrients. The plant looked great a week before.

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...

Deficiency issue/problem with leaves
Any idea what problem I’m having with my plant/leaves? I’m guessing some type of deficiency because I’ve only fed once and it was a few weeks ago. (Check photos in most recent week). Any advice/ tips would be awesome, thanks!
