I think your plants medium is changing so much it doesnt know what the f*** to do.

is it just me or are those pots really small they are in?

12 litres of good standing water through each of them, and then let them stand for a few days

they will be ok if you can get the ph to 5.5 - 6.5 stable

the stregnt sounds fine on nute

i just think you hit that baby with too much different shit at once

all those chemics

you marilyn monroed it mate !
