Is overgerminated barley malt beer harmful ?

[Nebihnebih]

My barleys are germinated too much which greens are 2 cm. +-1 cm. Does grains contain harmful residues for the beer i will make ? I know if onions, garlic, potato etc. are germinated, eating them are harmful couse their bodies collect harmful phosynhtesis residues.
Thanks in advance for your opinions.

Over modified malt won't have as much extract potential since the plant has consumed more of it's starch reserve.
