Both those fertilizers are NOT SUITABLE at all for cannabis.
For growth you want something around 6-2-4 and for flowering something around 4-4-6 for general feeding, supplemented with some cal/mag and a P/K booster for flowering.
I would say your plants are suffering from toxicity due to a nutrient salt build up in the substrate.
Plain water for a week then resume feeding with proper cannabis friendly nutrients would be my suggestion.
The older damaged leaves will not recover, but this should help prevent things getting much worse, although generallly, what is ahowing now in the leaves, is a reflection of what was happening in the soil two weeks ago, so things will probably get worse before they start to improve unfortunately.
But getting the correct type of fertilizers for cannabis growing should be your first priority.
