Ok,then i feed with mother earth at ph 5.8 when its time to water..I dont have cal/mag,that will be very difficult for me to get a hold on...This is alle the nutes i have: Biobizz grow,bloom,topmax,fish mix and alg-a-mic. AN mother earth tea grow and overdrive,and no mercy guano extract. Can some of this be a good source of cal/mag?A soil pH of 7 is too high, even for a soil grow, let alone a soil less one. Soil should be about 6.5 You were given good advice when told to run it more like hydro. If you look at this chart you will see that with a pH of 7 in hydro, just about everything is being locked out, especially calcium.

Too bad you just fed yesterday as that would have been a good time to hit them with more of the Mother Earth tea. I don't think you need to flush, just wait till they are ready to be fed again and use the tea. I would adjust the pH of the feed to about 5.8 and check the pH of the run off.
I would also pick up a cal/mag supplement and start feeding it with every feeding. Cal/mag deficiencies are common with autos, especially when grown soil less.
Bear in mind when dealing with hydro store that it's pretty likely that they have no experience with auto flowering plants. They aren't the same as photos and have different nutrient requirements.
