First grow. Purpling on stems. Please help? PICS!

I have some girls that are 30 days since they popped dirt. This is my first grow.
They are in FFOF soil and in #5 Smartpots in a 3x3 tent with a 315w CMH light. I have been feeding them plain RO water pH'd at 6.5 with Seaweed extract here and there. 16 days into their life i gave them a 1/4 recommended dose of Bio Marine and CalMag+ from the General Organics GO box line with some seaweed extract, they seemed to love it. I fed them again 4 or 5 days later with about the same dose and they liked it. I fed again two days ago with the full line from the box as recommended for 3rd week of veg at a little less then half recommendation (i fed 4ml of BioThrive Grow, about 3.5 ml of CalMag+, 4ml of BioRoot, 1.5ml of BioWeed, 3ml of BioMarine and like 1ml of Diamond Black) and pHed down to 6.5 tested both with pH pen and pH test drops. My tent stays between 72 and 84 degrees during lights on depending on temps outside and at night i turn a heater on in room and it stays around 70-72 at night. Last night heater stopped working and it dropped down to 64. I cant replace till tomorrow. I just ordered some Mammoth P and ReCharge aswell. SOOO... i just noticed today that on all of my plants there is purple on the stems. Mainly on side branching but there is some on the new growth where i topped and a faint little amount on the lower main stem. It seems the purpling is only appearing on the ridged parts of the stems as seen in pics and on the fan leaves part its is spotty looking purple also as seen in pics.

I really need your help. I want my girls to be hurt.

First of 64 is not too low of a nighttime temp. My rooms stay at 75f lights on 60-65f lights off. I run 40% rh the whole time. Now on to your purpling. Your plants look normal to me in those pics. What strain are you growing?

I havent grown either of those but they look fine to me.

I agree, they look great.

but, maybe narrow down your parameters? like pick a nutrient line and stick to it, no need for all these additives like mammoth p really, but its all good. yours look swell, good job!
I never had an issue with any line when I followed the directions, until I added other items......fyi

Some times your line of nutes doesn't particularly cater your plants needs, thus the need for additives

MAmmoth P and Recharge are just benefical batericas for the soil.

Honestly they look extremely healthy to me, stems purpling is somewhat normal i wouldnt change a thing your doing except i did notice in a couple pics what looked like nute burn on a couple fan leaves, looks like your growing in FFOF are you goin all organic i take it if so that soil is super hot especially if you added wormcastings to it, i would give her just some good water for a few waterings and see what happens but like i said they look awesome to me. Curious when you mixed up your FFOF did you amend it at all other then extra perlite i noticed.

Literally just an extra cup between two bags of soil of perlite (all the perlite i had on hand) and i potted straight from bag. No adds. I always heard light nute burn (im assuming something like what mine looks like) is good, means my plants are getting max amount of food? There is no advancement of yellowing... those nute burnish spots are literally right at the tips. But as far as im concerned, this is all organic. That burning on the lowest node of leave was a bit of burn and N def 14 days in veg.

Yep im fixing to do gorilla glue in FFOF my first run with it i have amended it though with several diffrent organic additions, ill post it all in my grow journal in the next few days when we are able to upload pictures. my ph on my soil is right at 6.9 which is ideal germinated my 2 seeds in less then 24hrs in paper towel stared monday 2 plants are already in soin about inch tall and have 2 already distinct leaves other then the embryo round leaves. this soil is gonna be awesome will just have to water and go lol my first grow with smart pots also im using the 5gal like yours here they are amazing to use so excited about that.

I have roots clawing out the bottom of my pot already lol. FFOF will not go the whole grow without nutrients being added later into their life. /i heard there is like 3 weeks of nutes?

Looking great buddy

A little purple on the stems isn't anything to worry about

Well i added a bunch of additional ingredients to it lol wormcasting tomato tone and kelp meal, and will probably add a little more worm castings lol dont think you can give them too much wormcastings i grew a plant once in straight wormcastings not soil just worm castings and perlite best plant i ever grew.
