Sorry for the lack of photo but just wanting to know how can you tell the difference between the root PH being off or if a plant is underfed? My heads not been with it this last few months obviously, to those who know why.
Got x3 chembubbly autos in coco under 600w hps. Temps, humidity spot on, plenty of airflow etc.
They're about a month into flowering, canna A+B PH down to 5.8.
1 of the plants stayed short and stout and is fine (if not a tad Nitrogen abundant) but the other 2 stretched a lot more and have yellowing leaves and bud developing very slowly compared to the short plant. It didn't start from the lower leaves, it just started in patches all over. Upped the feed in stages to 1.6 EC (my tap water is around 0.2).
Planning on flushing tonight or tomorrow but just wanting to check. Cheers guys.
