yo yo brotha Nesta. What it be growmie? Girls are lookin strong brotha. You know what I know and don't but I wanted to chime in as a fellow blummater.
I think it is more a matter of watering too frequently since the
blumats if become "un-dialed in" can cause there never to be any dry-back. Maybe the girl in question is less tolerant to over-saturation at the roots. Does that plant ever get any run-off? It seems many say you shouldn't get run-off in soil but also many others say it is important that you do/can.
I just learned 1st hand what has been fkin up every one of my grows and it was poor watering/ferting practices mixed with fabric pots. Fabric pots were causing me to have a rootball in the center and bottom would never dry back while the exterior and top would. Only by cutting her out of the fabric pot carefully and placing in another one did I see I was dealing with cake mix powder soil rather than healthy living. No wonder Puff fkin hates me hah
That's my 3 satoshi brotha. I would say likely none of it is accurate/right but hey you know my heart is in the right place for tryin
