Help! please.

I have this pretty tall plant its is bushy also i noticed the other day alot of the leaving are turning yellow the brown and dying what can be the cause of this? It's this one you can't see the dying leaving because the are toward the middle and down inside the plant. I hope these new pics help took them today.

what are u feeding them....how often do u water??

I feed it fox farms tiger bloom. I gave it some fish fert 5-1-1 yesterday because i thought it needed nitrogen. I water them 2 times a week sometimes more. Hope this helps

You something wrong that's for sure. I look at your grow journal~
The skinny leave like I never seen before~

I don't understand what you are trying to say.
