Can someone please help me identify the problem my White Fires show no growth, with just tiny bonsai type leaves appearing but stalling out. I checked the roots of three White Fire cuts tonite, and there is little to no root expansion out of the rapidrooters Everything is top of the line, Heavy 16 nutes, Aptus supplements, compost tea, in coco and perlite, fed at about 1.0 EC drain to waste, 5.8 pH, under multiple 1K HPS in sealed room with AC and CO2.
It might be real nice to give them some light in the 6500 kelvin range rather than the 2700 kelvin you are giving at the moment, see how tall and scrawny they are. Only 3 plants under a 1kw light is a bit extreme, I'd go 400w Mh and 400w Hps for these 3. Ease back on the nutes too, those red stems, will prove to be a P/K lock out eventually peace "V"
