This is an old label I posted on a completed grow thread, on another forum. Mixed Hydro - Coco/perlite .. FNB feed as ppm, starting low and raising the PPM.. The 3% citric, that was removed, dropped my ph a full point when mixed.
Have been thinking of adding 3% citric back to a new qt bottle of FnB that's missing it.. I'm afraid it might cause certain parts to precipitate out. Would hate to waste 25$. Any opines on this?
