Good to hear it. Now you'll recognize it, if you ever see it again.

I was puzzled because, as @etruthfx mentionned, there was some signs of micro-nutrients deficiency...
Anyway, really glad it all came back! they look fantastic now!

Should have mentioned if your media/soil temps are too low, plants will can become mag def, took me week to figure this out several years ago, was winter my planters were close to the floor... something for the roll a dex...

I calibrate it each month (blue lab) Ph was ultra stable and still ultra stable... It just started to climb a little bit since the ionic exchange due to vegetative state. (ph tends to rise in veg and lower in bloom).

Make sure you check those blue lap pens they miscalibrate and read incorrectly after a while. My store said they couldn't do nothing about it I gotta buy another one. It reads 4-500 ppm under actual they tested it for me
