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.

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

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

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.
