ok so with that I would say you have a mag. shortage in your juice mix I have not used that co. stuff but look at your labels and see what one in the group holds the mag. and add like another 1or2ml.s to it and you should be fine. (if I had to wager a guess just based on the names of the nutes...
never mind just looked at pics
I would wager a guess that your soil is to wet and not getting enough air to the roots what is your watering cycle and whats your juice mix & how offten are you juicing your plants?
it could be either to much water or your nutes are to hot on the mix or a combo of both hit me back with indoor/outdoor and soil or hydro. more than likely it is too much water
