Just "addopted" some new girls

First off i would just like to say i love this forum learning a ton

So i have 3 girls from some dank purple i had bought that i have under a 250wMH they have been going great.. i just topped them the other day. Now a friend bit off more than he could chew and i took in 2 of his girls Heres the kicker. his are an autoflowering Lowryder#2/AK47 but hey i couldn't turn down and i didnt want him to kill them there already flowering. they have single white hairs on most of the branches. so now i gots 5. but.. they are in some MG potting soil.. should i be giving them any bloom formula? there on cycle with my other bigger girls 18/6.. never messed with Auto's any advice or pointers would be appreciated.. can answer any questions.. realy reaching out here

How long in the mg soil? I would only add nutes if theve been in there a month or two.

I don't think it's been that long. Wondering if i should add any bloom formula or anything since there AF. And if possible to keep these 5 in the closet and get them to live together.. i'm probably going to have to keep my other 3 in veg untill these AF finish unless the LowRyder#2/AK47 will take to the 12/12 when i switch .. ??

honestly i would switch from that soil as soon as possible hat soil is good for vegging but not in flowering as it probly contains high nitro so mix up some new soil with no or lttle amount of nutes... then add your nutes that you have to feed them never use pre nuted soil, if helpful dont forget to +REP just letting you know from experience
