Day 31 of Flower ...Lower Leaves Drooping ok?

[GrowWithTheFlow]

Whats up everyone.. first grow.. everything seems to be going well.

Runoff PH jumped a little more than i would've liked from 6.5 to 6.8...with regular ro water today. PPM of neut water I try to hit low 900s or high 800s

Plant is responding well, lower large fan leaves are starting to droop, think i will defoliate some on Sunday.. is this a good idea?

Pics & Vid below.. as always alllllll comments are welcome! Thanks

Did you ever figure out why? My plants are doing the same thing and they are 34 days I think five or take a few without checking my book
