First Timer NEED HELP salt buildup!

At the base of my plants there are tiny crystals building up in the soil...i was watering straight tapwater but after learning about the harm in that im using fresh water and boiled water only.the plants themselves stink! how can i fix the salt issue? i used 10/10/10 miracle grow above ground fert.only because its what i had layin around they are in 3rd week of flowering,outdoor one more thing can anyone tell what type or strain my plants are?I will get better pics asap these are a week or so old they have FATTENED up

Give them a goood watering

yeah fluhh them out MG is known for salt buildup

Flush them good at their next watering and you should be fine. If you don't have a PH tester or PPM meter then buy purified water from the store.

I did that for ahile, but it adds up $$$ long run. Just go to lowes or gome depot even and get a soil master ph tester for like $10. I know it aint the most glamorous but its saved my plants to this day!
