Purple Stems On Mother Plants

Title pretty much sums it up. My plants from seed grow fast, green and healthy but my mothers always end up with purple almost woody stems. Anybody know why this is?

purple stems can be showing a defficency or low temps but ime this condition is mainly genetic

Really, you think it could be genetic? It seems to happen to all my mothers eventually regardless of strain. The temps are a steady 75.

fertilaze them with dose of P ... cuz u got your mother plants on vege right? and u fertilaze them with vege fertilazers right? ... for veg. fertilizer got less p then n or k ... so if u fertilize them always with that fertilizer then u will get P defficency ... so i suggest u fertilize them with small dose of P but this is just imo.
 
Good luck with your foundation plants.
i honestly sometimes brew a 50/50 veg and bloom tea not at full strength and feed.
i feed momma AN Iguana Juice GROW and AN Mother Earth tea BLOOM when i mix veg and bloom together;

i also use kelp, molasses and BIOGENESIS mineral Matrix Micronutrients occasionally.
hope your mommas are healthy and live long
 
id say its ur temp changes or genetics dont get all worked up over someone saying its a deff a deff of what i didnt see anyone put a finger on it but one the very first person to post ya im goin with temparature feeding bloom nutes during veg is absolutelly a waste of money and your time
 
Im gonna mix up a half strength bloom fert. and see what that does. One thing I was wondering was if I do fix it with the P. will my old stems change from purple back to green or will only the new growth stems be green? And what temps make your stem purple. Low or high? Thanks everybody for all the input.

low temp. makes purple color under 15*c around there .. new growth got to be green or alse it not deff. P
 
Defeciencies as a general rule of thumb appear on older lower growth first.
Phosphorous is a mobile nutrient which means it can move from one portion of the plant to another. EX. P that has gathered in an older leaf moves to newer growth.

PHOSPHOROUS deficiency causes stunted growth. Leaves usually smaller, bluish-green in color and stems turn purple/red from the underside, though as others pointed out purple red stem is not necessarily a deficiency. Do your older leaf tips curl downwards like a claw?? Maybe P is present in your medium but is locked out by other micronutrients or high PH

The gentleman/woman who posted their question said

If all you're seeing is colored stems in your mother plants and they seem otherwise perfectly healthy I'd probably just ignore it. It's not likely, but it is possible that the multiple strains you've got all share that particular trait. And regardless, if things look healthy except for that it's probably not a significant problem. If it ain't broke don't fix it till it is.

Phosphorus deficiency can be pretty easy to run into growing mother plants because most grow nutes are low in P and if you're using something like VHO (awesome stuff, btw) you're boosting your N and K even higher in relationship to the P.

As has been suggested here an easy way to combat that is to just tone back the grow nutes and mix in some bloom nutes every once in awhile. I've had to do that once or twice with my mother plants but I actually tend to just give them a dose of a bloom booster like Big Bud. About half what I usually give them in flower.
