nothing major to worry about aslong as you keep an eye on the ph and gradually reduce or higher it also stop spraying.:thumbsup:
blueberries tend to have that trait. spongy medium most likely is rapid rooter, ditch the thrive alive, your plants look healthy otherwise as ive seen this a time or two, ignore and get some cuts if it doesnt become problematic. usually they grow out of it and do fine. i dont see anything your doing so terribly wrong that would adversely affect you.
