Nitrogen starts from the bottom up. Not sure thats a nitrogen deficiency.
True that. Seems everything in the shadows is a nice healthy green. pH out of whack maybe locking out micros would be my guess. Some burnt and curled tips on the upper lime-green leaves too.
Hmmm . . .
could be pH out of wack or just a food deficiency for flowering. I would add a little silica, and be a little heavier on K and a little bit more P... But I would make sure the medium isn't clogged out. You may benefit from a small leeching to get rid of excess salts so that way you can push the pedal down. It could also be a watering infrequency problem causing bad pH and soil salinity problems, if they are outgrowing their space!
I doubt they are outgrowing that space, those planters look nice and big so I would bet on parts of the soil getting a little to dry vs the other side, or some sort of pH problem ( probably due to moisture stress), and that is causing lack of uptake. They want to thrive and something is off
what do you measure your ph and ppm with and what nutes? what soil? and what is your "regime"
Nearing end of week 8. I cut the co2 and dropped the temp and humidity. Only getting water from now on.

Why only water? Those plants are in the final phase where they pack on the weight and bulk up. Denying them the food they require to properly go through the final finish phase doesn't make a lot of sense to me.
Just what I've always done. It's an organic grow, so I don't usually add anything unless they are showing signs of hunger, although this run I did supplement some food after week 5. The last two +/-weeks they get to use what food reserves they have stored or can pull from the soil.
I don't need road flares...
I might try it another time. This run I just want to finish clean since I had issues with light and heater stress.
Looks good I would say those have 4-5 more weeksNearing end of week 8. I cut the co2 and dropped the temp and humidity. Only getting water from now on.
