Are you feeding by liter or gallon? I'm sure someone with more skills will come along and help you out but looks like need some more P and K.

ml/L
I was thinking the same, but I'm increasing dose, but they still not getting better maybe I should cut all nutes and give only bloom?

by the time they are in full flower, you shouldnt be giving them grow anymore. I use advanced. U can check out one of my journals for the nutrients I use. What is the rate u are feeding at? are they metric or standard measurements? It could be a lot of different problems, and the more detailed you can get with your info, the better. are those ml you're using as measurements? is the rate per gal/litre? how much in cup/oz do u give at feeding time, and how often do you feed? do you give them fresh water? they look a little burnt from nutes, but it could be a lot of different things. good job taking so many photos.

I updated first post for more clarity.
I use ml/L. Single plant is getting around 400-500ml. I can't tell exactly, because I'm watering from the same watering can.
Only yesterday I gave fresh water about 200ml per plant because I was already lost and didn't knew what to do.. Before flush I was giving only fresh water and only feed when I noticed deficiencies. But lately i couldn't control problems so I thought I better flush them and start from beginning.

Plant looks rather healthy over all. It is sacrificing mobile nutrients from the leaf to move them to the buds. If the new buds look healthy I would keep the cool and just give water, let it sacrifice the leaves and suck it all out. How many days until harvest?
