Wondering if you can lend me a hand. I’ve just mainlined my two plants at 4 weeks at the 3rd node. Now I understand some stress is going to occur but I’ve got the big fan leaves starting to change in some colour. Any help please!!!!!

In mainlining her you've just stressed the bejeezus out of her and that can be a contributor to the discolouration as she sucks the required nutes from those leaves.
The leaves are a bit like the plants reservoir, she stores nutes in the leaves then draws on them as needed. Normally, she'll do so from the larger lower leaves first and looking at those pics IMHO that's what she's doing.
Now, if that colour change was occurring to the new growth, right at the growing point, that WOULD be a concern. But considering her mainline stress, she's had a shock, keep an eye on her (as I'm sure you will) but she's doing OK.
Just for your reference here's a chart that could assist in diagnosing deficiencies.

Why did you chop off all your growth , more leaves more photosynthesis
What you are trying to do well let's just say its a waste of time
Please tell me what you cut off you used for clones
The the part I don't agree with is the explanation of why
Without going into detail , the plants aren't using nutrients stored in those leaves , old wives tale , what they produce during the day is used of at night just to make it simple
Just because you have light for 18 hrs + doesn't mean the plant is in photosynthesis , it isn't
As soon as the leaves can't hold any more the process shuts down , so in fact they may only he active for 14hrs
Most nutrients will be in the stems , leaves are the factory, stems and roots the warehouse
The bigger the surface area collecting light the better
The reason your plant imo is showing brown rusts spots is high humidity low temperature , maybe insufficient air flow and or extraction
They don't look hungry to me
Bit of advice , leave it alone and let it grow
Sorry Merl , no offence
