Hey man, I just took a look at your Diary. I wouldn't stress too hard, you can still harvest some dope bud from those girls.
I would HIGHLY recommend feeding some calmag. Cannabis plants love that stuff, trust me.
Also, I believe you need to cut back on the amount of nutrients you're using. Way too potent in my opinion. I use fish shit also and I add 4 ml/gal to my solution.
Lastly, if you have the ability to, control your PH. I would recommend putting more effort into my first two pieces of advice but this will always help, and is important.
Hope this helps!
