Odd Growth and Colors Help Please

Need help with plants. Planted a few seeds in this tub and got 3 females just ripped out the males any way the all started at the same time but there all growing there own paths one is turning purp but its a horrible yield the other is the tiniest plant i have ever seen and the third seems to be growing fine i just dont know what to do with them anymore i havnt really been caring for them as much as my 1st plant last yr but its been fun just got a newborn to deal with now any how just interested in ideas and help cuz as u can see by the pictures im not doing to well with them all tho i cant wait to try that purp but wats turning my leaves yellowish redish purple?

what are your temps? what nutes are you using? three plants in that bin? not really a good idea

Well im in nyc and we have been having some very crazy weather lately and a very wet june and july between mid 60's and mid 80's all these months not this past 2 weeks been in the low 50's at night tho im assuming thats whats making the purp but i didnt know it would do it to the leaves but my leaves are yellow so i kno it needs more nute i just put in new miracle grow soil today and hope it getts better it was also in a smaller pot but not much space so i put it in this tub today as well and i havnt put in any outside nutes aside from wats in the soil

It's Diffffffentally the temp thats causing the leaves to turn purple/red-ish. If you're in NYC its getting cold this time of year, i hope you don't leave them outside..

Yea i figured it was that they do still stay out cuz its still no were under the 50's at night so i dont mind all tho i dont know if its safe or not but do love dat purp so willing to sacrifice it

Prupleing is caused by 3 things: cold temps, P def during vegging or molybdenum deficiency... or simply genetics, but in that case the whole leaf turns purple at once... most probable is the cold temps.

The yellowing is caused by poor light and cold, you should get your plants inside...

Wouldnt putting it in side effect the growth i mean its been an outdoor plant since seed and i dont have n e special lights or n e thing i did notice the leaves are now fully dark purple and the buds are turning nice dark pup aslo what are the benefits of purple anyway and wats a good way to let them grow soo i can get a better yeild cuz they look so skimppy it loos nothing like my plant last yr

The only thing purple buds excell in is bag appeal, nothing else.

Yeah, it's never a good idea to put a plant grown outdoors inside, unless you can actually give it the same amount of light and ventilation.

i brought the plant indoors due to the cold was to extream now its just in my boiler room temps between 70f and 85f and a decent fan question i have is wat bulb would be better daylight florecent bulb or flood lamp its all i have to work with or a reg bulb
