1st grow 4x8 flower day 42 help

I am brand new to this forum and excited to use it i should have started a while back. Anyways i am currently at week 6 of flower day 42 in my 4 by 8 setup. I have 7 flowering plants. I want to go over full details of my setup another time but im currently having and issue with my fan leaves. Im growing in coco coir i washed myself and amended perlite and some foxfarm planters mix with guano. I have been running sensi grow and now sensi bloom on my flower plants. I feel maybe i have a phosphorus issue or calcium issue going on i will take pics and post. Please any help is appreciated.

What's your PH levels ? They looked over fed or locked out.

I keep my PPMs around 375-650. Check your runoff with a TDS meter

my PH is usually 5.6 - 6.3 , check your PH run off.

What you put in should match what comes out the plant, if it doesn't just keep flushing till you're comfortable with the PH

I'm growing in coco as well

Im matching what i put in. I do not have a TDS meter yet. My run off is 6.2 as well as my 6.2 going in or very close to. You think they may be over fed. Thats very possibly. I have fed every watering for the past 2 weeks or so. I will run straight water threw them for a couple waterings maybe? I am on week 6 and planned on starting flushing next week for 2 weeks with a total of 9 weeks flower.

Here are some pics of other strains having no issues it seems to me. Maybe this holy grail 69 is sensitive to the nutrients im giving them. What should i do cut back on nutes or just run water with molasses? I was thinking just finishing out everything now with water and molasses so i dont mess up my crop..
