Everywhere i read deficiency this, too much of that will lock stuff out. Is there any general thing i can do to help other than flushing. Its in coco soil feeding ionic coco bloom, temp and humidity are bang on. the plants quite old being a cutting and it bubble gum, any ideas would be much appreciated.
