Leaves turning purple in onset of week 6 flowering

[Vdxiii]

Hi all,
I have this Gelato OG in week 6 of flowring that started showing purple leaves. Does this mean phosphorous deficiency? This plant was very short and very bushy with too many small flowers and too many branches. I think it is phosphorous deficiency so i cut alot of the small branches (very too late i i know but this is my first time ever to grow cannabis). Will this fix the issue? is the purple color issues normal? so many of the colas didn't gain that much volume and weight still which makes me wonder will i manage to achieve thick nugs in the 3-4 weeks left before its harvest? or this deficiency at this time of mid to late flowering means it won't grow big nugs and won't recover this deficiency?

Thanks a lot for your help.

Are the buds really sticky yet? Not a lot of trichomes production going on with them but I’m sure you’ll get some great weed out of them.

If you have cool nights that will start making them turn purple

@ganga gurl420 indeed the temp fell down to almost frost at nights, i keep them in the shed and keep the door open. will those cold temps affect them bad?

not that much stickyness yet and trichomes are not much? does this mean the quality won't be potent?

Purple is normal in cool temps. Not to worry. Looks cool, doesn't it?

It does indeed...I wonder if the nugs are gonna still put on more weight even in this cold temp till mid October!!!

@ganga gurl420 , @Hipster2U @Davmalk I did a mistake of pruning this plant to maximize yield but it was too late into flowering, I should expect this hinder the flowering since the plant got shocked ..correct?

What are daytime temps? Your buds will most definitely swell up substantially over the next few weeks.

Right now it is 9C-15C during daytime and we have been getting Frost at early mornings.. But I put in the shed at night

I must say reading this post was really insightful I had a problem and when u search purple leaves etc a problem always occurs..... (hence) I have a plant I looked up week5 and it was doing a purple thing w the leave but it doesn’t look bad or feel like pho’s or a mag def etc just feels different idek I chill w plants a lot and I don’t honk it is a def just fella like a high brix? So I’ve been told night time temps for me are low but plants seem to not mind them I am around 65-67

just 3 plant doing this not heavy as the first pic but only on topcola on each hit up breeder and was told nothing is wrong

@tko2184 they look perfectly normal to me bro...don't worry. Goodluck.

This is not turning purple, this is a deficiency (or deficiencies) as you suspect. It is phosphorus, and the timing would make sense, it is at a peak requirement. Address as a deficiency imo.

THIS is turning purple, as a natural effect of later in flower and temperature (imo).

Ok lemme clear this up..
Purple can be caused by a couple things.. its like a fat person.. can be food consumption.. can be a thyroid issue.. lack of excersize.. etc..1 issue can stem from numerous things..
Reading the posters temps.. no doubt its just from temperature fluctuations.. low temps .. 9 degrees celsius is WAY too cold for cannabis to grow adequate buds.. it probably barely grows at all tbh.. cannabis needs above 20 degrees celsius to even begin to touch their range..
Ive had plants get shocked by being thrown in my 60 degree farenheit basement.. cant imagine 10 celsius.. whats that like 50 right?.. you are lucky they didnt die.

The stunted growth and purple are BOTH from the temp most likely.
