What the hell is this

A. Feed soil, not leafes. B. Don't take your plant away from the light - they might think its switch and start doing crazy stuff.

CaMg in the medium not the leaves.

I would just avoid foliar feeding untill down the road.

Thing about spraying leaves, calcium is immobile within the plant so once absorbed through the epidermis of the leaf it can't be reallocate down the road. Your leaves all have calcium sickness. Magnesium sulphate is a much better option as magnesium is what makes the chlorophyll core and is mostly mobile within plants when in excess.

Looks like it might have been a little hot, when adding something new start with a weakened dose just to ease the girls in. You might lose a few leaves but hopefully they pull through. Good luck bud
