Good evening fellow growers!..
(A friend) of mine has a setup in a 2 by 2m Tent with 2 x 600w halogen lights, First attempt with AUTOPOTS at flowering, 100%coco ,4 cheese 4 lemon haze always been top fed past 3 years, temperature is around the 28's never dropped below 20's so its not getting too cold.. Started of with the Stems going purple then the leaves yellowing and crisping ? Cant be over fed as the guide lines have been followed on the nutrients? first time using this feed as Canne and dutch pro was previously used and thought to try another , theyve had a week of straight water and revive with still no good results and still yellowing of the leaves! thoughts were lack of nitrogen was the cause but?... Baffled!!! must be 2-3 week into flower buds are looking appauling to what they should be!

What where you other things? Any help is appreciated
If everything else is "OK", the only thing that comes to mind is a bad pH situation. Have you checked the pH?

Those yellow leaves indicate that they are not getting the required nutrients. If you're feeding the right stuff (but they're not really getting it) - I would suspect nute lock-out caused by your pH being way off.

PH was tested and it's fine I eliminated that problem, I don't know why the stems are going purple though?.. And does under nuting cause the leaves to crisp at the end? I thought that would of been to much causing nutrient burn, been another couple of days and the revives done nothing, I am well and truly stuck on this

So you're saying they're over fed then?.. I'll half the dosage to what it says on the bottle, also, am using these autopots which keeps them quite highly watered, worth giving them afew dry spells??
You have a deficit at this point. This can be a seesaw thing at this point.

By your answers to previous questions, I'm inclined to say -
Classic too much P&K too early!

Nothing to do but maybe attempt to hit with some N to slow down the progression.

Next time - NO bloom feed till the start of week 3 of bloom.

Hard to understand some of your explanations a bit....What is your pH? How do you know it's ok? It SURE looks pH related too.
Do you do a minor leech with that coco from time to time? How often?
Did I understand that you "changed" your known nutrient line to something new? What one?

I do agree with top feeding coco.

lets go from there and see If I have a follow up

I would start by flushing them really good. Then let them dry out before giving them a feeding, or even give them one more regular watering to see if they respond at all. If your plants are sitting in nutrient build up cutting the feed to half strength is not going to help in my opinion. Your still adding nutes to a nutrient rich medium. Perpetuating the cycle once again. You need to start fresh and flush them.
