i think its nute burn can u help?

I been getting this diff. for awhile now. and it seems to be getting worse.

i use fox farm ocean forrest soil with all the 3 nutes. grow big, big bloom, tiger bloom. Im told foxfarm soil lacks cal and mag.

Im hoping this isnt bugs i dont have my scope in yet so i cant tell. anyways.

this is my first week flowering i think im getting signs there all female. so i went and bought cal -mag from botanicare and used it 2 days ago. Question is idk if its a diffeciancy or if its bad ph. all i have to read my ph is a ph tester kit for the water. so once its in th esoil idk if it changes or not. i also have a ppm pen which i havent really tested anything but the water that cam out when i watered. so heres some pics telling me what u think and what i can do. and im growing la woman and blue cheese there really short. then i have one tall one lol thats just a bag seed i had i think its og kush tho.

also one more thing since i had the plants id water every 2 days and feed every other watering with a tsp of nuts to a gallon or so whatever it says on the bottle.
week 7 first week flowering

Too much water and too much nutes.

Learn to water by the weight of the pot, not a schedule. They need to dry out some between waterings.

Nutes ... Weekly, Weakly

Wet

lol thanks man appreciate it. i been running a gallon of water through each and there 3 liter pots. i usually check the soil with my moisture meter and when its dry i water. So how much water do u htink i should use like 1 gallon between 2 pots? also these leaves are dry as hell do u think if things get better they will get better or are they done for already and are gunna dry up and die off?

whats everyone else think?
