What soil is it in ?
How long has the plant been in flower ?
What nutrients are you using ?
Exactly how much have you fed it and when ?
Looks like a nitro def although MG is typical in week 3-4 of flower but I cant be sure until I know what you have given it.
More info needed Im afraid.

Over Fert ! IMO Straight up!
I rarely hit 4ml of biobizz bloom a litre and you are supposed to be using 1 ml of bio grow right the way through the cycle, it contains allkindsa sugars and b1 to help your plant thrive.
Got a PH meter or EC meter ? if you dont go and get one or at least some PH drops. I will bet the PH of your runoff is below 6.2 possibly even as low as 5.8 and it will have an ec of anywhere around 2.4 ( I have grown a lot of biobizz and my first mistake was just like yours).
I could be wrong. At 3-4 weeks the typical deficiency is MG. I would say you have a lockout caused by too much P and K and it has dropped your PH massively. Did you add Lime to the allmix ? I highly recommend lime and perlite when working with allmix.
I use a 50/50 mix of bio bizz all mix and gold label special mix with an extra 20 percent perlite added. It rocks because the allmix is restricted on a lot of minerals that they can use to stay organic where as the Gold label special mix has swedish clay (mineral rich) and added lime it makes for a much more complete soil.
Do not take anything at face value and always ensure that the diagnosis is correct before you treat.
This is just the stoned ramblings of a guy who likes to grow pot. Take it or leave it

EDIT : The smallest pot I run is a 7.5 and I have since abandoned them in favour of 10's and now I am abandoning 10's in favour of 15-20 litre air pots. You may want to find a bigger one. Check greengrocers and florists for buckets and drill holes in them, mine cost me 20 pence each. Costs me a quid for the bases lol

50 litre is excessive. Try 15-20 ish 
Larger plants have larger veg time. I grow medium ish plants and veg shorter and grow more. Yet again thats just my preference. I know a guy who grows tree's in 100 litres of soil at a time ! He yields great.
Have a look at my journal its here ! https://www.rollitup.org/general-marijuana-growing/465639-my-never-ending-quest-best.html
I have lists of my gear and nutrients spread around the 5 or so pages.
Hope it helps.

I disagree with the idea its overfert. I have don ethis, and normally the new growth shows burn, not the old. But thats just me, Ive had plants with off ph and lockout,
IMHO it makes sense for the energy in the bottom leaves ot be used, and the nutes or whatever, if there is not enough from the soil.... just my thinking.

Its not the salts burning the plant, its the salts causing lockout and ph change I am suggesting (most likely due to the lack of lime). My critical mass have just started to lose a first leaf or two at week 5 of flower. I will let them die off in the last 2-3 weeks but man those are the plants batteries, its power generation. And if the leaves die for anything other than to feed the buds with sugars then I consider it bad.
They look exactly like my first bio bizz grow. We will know the answer if the grower can get a PH or ec runoff of the pots.
Jmward May I suggest you listen to everything but follow whatever you decide is right. Never take a single opinion as gold.
Hope this is helpful.

It may need Nitrogen.
Be cautious though you can kill your plants quick if you toxify the soil with Nitrogen.

*i wonder if Azos could help sort out your N prob... might be worth trying
