Shooeyanswered grow question 4 years ago Hi mate. I dont know about grey water but i presume you feed all plants with it, and the other one is thriving! So its just this fella suffering right? For me, it looks like its revegged, struggling in the cold and overall a bit of a runt. I probably wouldnt persist with this fella and have another crack when the conditions are better. Plant 2 is pumping along nicely!
