Each set of leaves has had this. Any ideas or suggestions?
Sorry just added
You’ve got a calcium deficiency. Do you know your Ph?
Ah ok. It is one strain. All the rest are fine. Should I add calmag and how much?
The PH is 6.5
Yes, add some Cal Mag. She’ll be fine. Usually it’s a teaspoon per gallon of water, but you should read the directions on the bottle.
