are you growing in soil. i use Bio products as well i grow in soil and was told not to use cal mag its only for hydroponic growing. im using bio grow, bloom and heaven.

you either have nute lockout or are very low on nitrogen and magnesium...

Those lower leaves on the smaller plant look pretty crispy. I'm with boo, this looks like a potential problem with the soil Ph and the root zone is not happy about it. Ph issues can lock out nutrients, even if they are available in the soil.

They look limp, is it possible you have over watered them? How often do you water and at what Ph do you water / feed?

Are you in soil or coco?
