In an article on aquatic world i found this as a definition for phosphorus deficiency. However i dont understand the line on ph range dependency? What does that have to do with P? Also my fast growers have burnt looking leaves but my P is over 10ppm, what else could cause this? Light is 2-3wpg, co2 is high, drop checker always green, all other ferts are in excess, i do weekly 50% changes. I have anubis that are flowering and no old leaves that look almost black.
Phosphorus (P)
* Symptoms: Small leaves that may take on a reddish-purple tint. Leaf tips can look burnt and older leaves become almost black. Reduced flowers or seed production.
* Sources: Compounds containing the words 'phosphate' or 'bone'. Also greensand.
* Notes: Very dependent on pH range.
also what is this:
Witches brooms sometimes form
Says its due to boron being low, i know my anubis have large roots shooting out with smaller roots jutting out in all directions from them.
