Ca def.
Idk about calcium def, with all do respect to slownickel, but my plants that had same issue were in rich soil.
I also cut those leaves off so the plant didn't waste any energy trying to mend them.
Hydroplex is good stuff!
If you like Hydroguard definitely look into Hygrozyme. It works far better imho and goes much farther. I use 6ml per gallon.
Decreased. No signs of stress after I started going to 1/2/3 + calmag every other time from 2/2/2 (veg/micro/bloom)
