What's your guys take on last couple days of darkness before harvest?
Purple

Hey,
Apologies if thread old but recently I have had a number of plants with more purpling than I can put down to a cold grow room! Often around main colas.
I am pretty careful with nutes but 4 or 5 weeks into flowering I often get rust spots and purpling of smaller top leaves. This time - pls see photos.
The plant was fimmed before flowering and flowering has been pretty explosive by my standards. I'm thinking deficiency, most likely phosphorus maybe. I am good with pH. Could it be too much flowering for 10l pot?
All thoughts appreciated.
Its a rqs White widow, day 80, 30 to go. Fert biobloom, formulex, calmag, etc varies but cautiously and foliar feeding for yellowing then "purple" top leaves. seems to be OK now but early days. not very sick at mo famous last words. Was thinking nute burn maybe too. thanks

Yes its a must.
Just a word of warning. Put mine into a dark cupboard for extra dark in last few days, once, forgetting humidity out of grow room. Patches of grey mould quickly super-negated any benefits. Was grown outside so probably was more susceptible. certainly would have helped hidden mould already there.

Can you explain your science behind the statement?

Just bro science is all. A bro passed the info on to me time ago so I try to pass it on to others. Not sure why the attack? I was simply answering someone's question.

No attack. I was just curious to the logic behind it. If you don't know, then cool. I'm not trying to put you on blast.

It's not an attack. It's been proven through testing that a dark period pre-harvest doesn't do anything.
We're just trying to inform people so they don't think what you are saying is fact or beneficial to their harvest.

Doesn't matter what's in your book. If it says 48 hrs of darkness is beneficial it's wrong.
Lets say his book is written by a top cannabis scientist? How can it be automatically be wrong? There may be good reason it makes smoke smoother or maybe increase a %. Who knows? He is telling you he thinks it works for him.
