Yellow veins, PLANT IS DYING!, Help appreciated.

Hello all.

I have two plants which are showing these signs, one seems to be bouncing back but the other seems to be dying, any input about a possible cause is appreciated.

STRAIN: Sin trabajo auto
Age: 9 weeks ... But both seem about 5
Medium: biobizz all mix
Nutes: biobizz, bio grow/bloom
Light: marshydro 300w led.... About 156 actual watts
Intake: 4 inch fan
Vent: 4 inch fan with carbon filter.
Temps: 28°c... Little hot but not overkill
Humidity: 33% .... Again a little high but shouldn't cause this
Water: tap water with a pH of 7
Pots: not sure how many litres but estimate 7-10
Drainage: good

WHAT I TRIED.

Epsom salt:
My first thought was a mg Def because biobizz commonly causes these problems, so mixed up a Epsom salt spray.. no effect, realised the symptoms were the wrong way around.

Flush:
Flushed with about 10-12L of tap water with a pH of 6.8.. no change

Feed:

After much research heard this might have helped so I fed 3ml bio bloom and 1ml bio grow.. leaves have dropped like over watering, had previous signs of n overdose in the past so it's hard to tell if leafs are turning into claws. No signs of recovery.

Current:

Yellowing of veins is creeping up the plant, a fan leaf by a bud site is starting to show signs and does not seem to be slowing down.

I will post pictures below in a moment

It is easier to assist if you turn off the light and turn on the flash. Very hard to diagnose under led or hps, your plant could be showing more symptoms that can't be picked up under current lights.. I picked this up somewhere, probably even this site, so no intent to steal someone else's work...

Stop watering it so much.

Do nothing but let it dry out. Then feed the poor thing. It needs N bad. Also needs mag. Mix the Epsom salt at a teaspoon per gallon and water it into the soil.

Already tried Epsom salt as a spray with no joy, I also gave her a decent feed including grow nutes which is packed full of n, I'm by no means a new grower and have came across most plant problems but this one is really getting her and no matter what I do she doesn't seem to be getting better.

No problem, appreciate it :) .. as mentioned in the last comment I have came across and fixed a large number of problems but this one seems unsolvable, first instinct is mg, nope, p, nope, even with claws a nice helping of n, nothing, flush, nothing... It seems as if I might just have to ride it out until her wheels fall off because I've hit a brick wall.

I didn't say to spray it. I said to mix it in your water and feed her some more N.

Mainly quit screwing with it and let the soil dry first. That dropping is from too much water.

Had a light bulb on moment.

In the panic of a dying plant I forgot to test the one thing that I would have advised someone else to check first, the f@#*ing pH !!!!!!!.

What a d!@k head I am, the pH of my run off was 5.3, which is why I have seen m, and p problems that are not reacting to treatment because they both get locked out under a pH of 6... I really can't believe I just overlooked it.

Only problem I had is no pH up to hand, so done quite a lot of research and I have tried baking soda with my mixed nutes to raise the pH, not brilliant because it can build up but no canna stores near me and can't wait for a order online. Run off has shot up to 6.3 ph.. if things get better I will make a thread about using baking soda with before and after pics..... If not..... Someone had to risk it
 
These are definately over watered. Stop watering and let them dry out. Hopefully once they dry out they will start drinking again. Keep humidity up but not too high and turn down your lights while they recoup. They will. Believe it or not it is very hard to kill cannabis if you dont over think it.
 
This is not a ph issue. 5.3 ar run off while low is not terrible. The baking soda most likely will kill it if you soil drenched. Not good.
