Rootbound, PH? Help Please.

I have posted and asked the question in our grow journal, and there is additional information there. Here are some pics of leaves from one of our plants, 'Lucky', and she is having issues at day 34 of flowering...I think it is rootbound...but I need some help. Please read the grow journal and tell me what you think. Thanks for your help everyone!

looks like nitrogen deficiency...which is pretty common at that point....maybe leach the pot and then feed it some veg nutes...imo

here is how you properly leach your pot...I do it to all my plants every couple of weeks to prevent salt build up..
