400w Pineapple Express, Bubbleicious, Northern Lights

So I started this grow on may 22nd and vegged for 3 weeks, just put it into flowering and moved them from small starter pots to 3 gallon pots and they have been topped. I have a 400w Hps/MH light and i am using fox farm ocean forest soil and will be using tiger bloom for the nutes. Now I used Grow Big nutrients for about a week and noticed weird shiny brown spots so i stopped using it and now they have turned into yellowish circles but its not really any signs of nute burn, help with that? almost all my leaves have atleast one small yellow dot, I just dont know what it is

The back 3 are PE, bottom left is NL, bottom right is Bubbleicious
