Possible but range for Coco is 5.5 to 6.5 so that was in range (I think Flora Flex recommends a range of 5.3 to 6.3 for their nutes)
I’m just thinking out loud here how often are you watering and how much volume per irrigation? Maybe you are over watering?
Example this girl I haven’t watered in 2 days
I was feeding 300ml every 2-3 days.
Sounds perfect to me. I was doing 500ml
Looking really nice!! 
Only thing I would think About it raise your exhale bag height up over the plants. Co2 is heavily than O2. You want the co2 to fail on top of the canopy.
Looking good 
So in a matter of 24 hours she now resembles a shrubbery!
Looking good!!! 
Some beautiful symmetry going on there! Looking nice! If you got the room I bet your GG#4 will take up all of it 
Wazzup, Jack?
She is a bushy one, that’s for sure. Going to ScrOG her as soon as the two nodes on top open up some more.
Hoping Jack can catch up to her, both of them are “fast” seeds.
That stem does look pretty thick, gonna be a tough plant! Looking good
Just trimmed off the two lower fan leafs, and this is how f’ing big they are. Keep in mind I have rather large hands, my wrists are 8.75 inches in diameter.
She is looking really nice and healthy
