What's going on?

Hasn't grown since yesterday haha, funny made me laugh that 1.. She was probably on a good wet dry cycle and suddenly you've give her too much water, killing off the roots, suffocation, dry is as important at wet.. Good luck

that really isn't a compatible nutrition program or combination IMO... unless (i) your chosen products are solid salts or (ii) your chosen products have solubility/precipitation issues with tap water, you should likely steer clear of RO unless fully able to touch on what RO water is, what the difference are to tap, the pros, the cons, and the true nuances... you gave them unstable molecular water and a microbial inoculation, and didn't mention anything else that would provide nutrients or life for the plant...the microbes need food at a bare minimum plant looks more moist than it would like to be, which brings light intensity but also just plant health into question. why is the plant not reaching your expected water uptake? were you wrong or is she stressing?

is it soil or coco ? if 2nd then u shouldn't water with RO water😗

hey 👋 Hard to say... The soil may be too wet, and the light intensity a little low
