Light: Mars ts-1000 and a 150w hps (stopped using the hps now)
I fertilized with organic seaweed extract ,biochar and bits of chicken manure.


What would be going wrong? I am not using any feed

How old is the chicken shit? Has it been composted or is it fresh? Growing up i had a friend who's family ran a chicken farm. The places where they dumped fresh poop had nothing growing around the piles but where the piles sat from one or two years everything around was growing awesome. I can only assume that fresh chicken poop may have bad bacteria at first until it composts. Just a thought.

Probably just a sign of overwatering leading to a lockout with possible pest infestation. Just guessing

I have replanted the plant,
Could it be due to low humanity?
Low "humanity"? Probably not. Low humidity? Not likely, but considering you haven't mentioned anything about your environment, we'd be guessing at best.

no

you need to let certain organic compounds "rot/decompose" for some time otherwise there are unwanted reactions going on on the soil (if indoor)
Would it be ph fluctuations?
I added fresh warm coffee grounds,biochar & seaweed 1-2 days before this happened.

pH fluctuations may be a side-effect to it. thing is that the initial breakdown of organic matter largely involves fungi (mold) and also "bad" microbes (anaerobe bacteria) which do create a kinda hostile environment for your plants.

Usually when one does composting of green garden stuff or organic kitchen leftovers, these guys are, at some point, repressed by the good microbes and then, ther organic compounds are also made more available.

Although the last poster of your link arrives at the right conclusions, he also does confuse something:
"Cannabis plants like a more neutral to ALKALINE soil, NOT at all a neutral to ACID soil. "

When, in fact:
Soil: pH ~6.5 ( 6.2 - 6.8 )
Hydro/ "Soilless": pH ~5.8 ( 5.5 - 6.0 )
