All mix for autos?

Hi all, heading says it all, usually I use bio bizz light usually with added perlite, but due to this Corona virus all local hydro stores are either closed or have no light mix. I was wondering.
1) can all mix be used straight with autos or will it burn them.
2) could I mix say 30% plain coco coir with 50%allmix and 20%perlite? Will this ease off the burning

99% of the autos survive np.

but.

there will be a slight tip burning from the N and a deep color around 4 to 5 weeks for not long.
For certains plants wont be slowed much. First weeks are impossible to be burned and then when the flower stretch starts, they use the N from the mix better. Actually when I first started I did a budget grow with all mix and only bloom biobizz nut. Didnt go bad. Around 30g with auto genetics of 2011.

I ended up using a mates all mix from a previous run that had been flushed through,
put it on top half of pot with regular almix bottom half

yeah good idea but it doesnt work well. the plants go under like the go in their tops. like they first stretch and then open up and get bushy. same thing with the roots, they first shoot it down to the deeps and then they open it up. but again, it should be fine. only a slight burning and some strains will not even notice.
