Hi all … long time watcher first time poster.
Plants start off well … I’m up to week 3 of Bruce banner autos grown in 70 coco 30 perlite. 250ppm … ive seen this before and things don’t turn out well.
See the dark centres and one of the fan leaves upcurling. Thought it might be a nitrogen deficiency but usually get dark green with that.
I helped a friend out in his room and think I brought whatever nasty he has back home.
‘The small ones are mine … and the larger plant is my mates
Any help would be greatly appreciated

Your ec needs to go up, your ratio is off, or your ph instrument is wack

Your friends plant is hot and getting to high ec
 
This is what happened to last harvest. Leaves get a real gloss look to them and the buds turn brown and die.
Broad mites?

that is a boron and a calcium def notice the tips of the leaves not fully developed ,lack of cell development

Calcium is highest at the leaf tip and new growth and is not mobile .
 
If there is plenty of both in your res, your doing something,to cause the meristem to not expand the new growth tells you a ton of info if you pay attention.

When you water try not to soak the top,try just watering the medium at the base.
