This plant has some problems; can anybody tell me what to do please?

This AK strain plant was doing well, but now I see many leaves are showing severe damage, but others nearby look healthy.
Please see the pictures attched. Does anybody recognise this problem?

Also I assume I should remove all these sick leaves...is this correct?

Can the leaves be used for anything?

Thank you for any advice

You definitely have some issues.
Can you give us some more info on the grow.
Media, nutes, lighting, and environmentals.
 
To grefranger...would bad pH and poor nutrients really make some leaves go bad/ die while others look completely healthy?

To gebauto; in coco/.pearlite using Canna A + B half strength nutreients, but no Cal Mag supplements (yet). Ph seems to be OK . Spider Farmer LED lights (12hrs/12hrs) positioned about 12 inches above the top of the plant.

Temp 22 C RH about 50%
 
Others might disagree but you can remove the yellow leaves, they won't turn green again. To answer your question, yes, incorrect PH and improper feeding/nutes will make cannabis plants do weird things. I had an outdoor plant that developed bud rot. It was sickening because a good bud would be right next to a flower with bud rot. Cut out the bad buds and you'll be OK or harvest the plant. I let my plant continue to grow because I wanted to see what would happen.
 
Seems to me i've read yes i've read alot about growing weed, that placing a LED to close has many negitive effects on growth. How can the Ph be OK? This plant has root rot totally mishandled. But go ahead and keep questioning about the answers to your questions. Nothing will improve what you've done to it, it's too sick
 
Suggest you go back to doing some research on the basics of growing cos whatever you’re doing isn’t working. If you keep doing the same thing you can’t expect to get different results
 
To Rwise - I did not use brick coco; I bought a 50litre bag of premixed coco (70%) and perlite (30%). I do not think this needs any preparation but please advise if I am wrong
 
I have only read about coco, never used it, but what I have read is it will cause calmag def if not pretreated. I stayed with my homemade organic living soil.
And yes all those dead leaves can come off (and should turn loose with a gentle tug), they are no longer useful.
 
All spotty leaves now removed...they came off very easily...can they be used for anything?


I will post another picture in a day or twos time...plant still seems to be ok and growing...
