Basically each kanji has some difference in meaning.

ๅตใใ (ใฏใใใ) (ichidan) to start
ๅงใใ (ใฏใใใ) (ichidan) to start
Normally ใฏใใใ to start is written ๅงใใ.
ๅตใใ is not commonly used... the kanji ๅต also means to start, but it is only used for starting business - in this case it is close to "to create".
e.g.
ๅต็ซ ใใใใค establishment (of a company) ๅต็ซ1960ๅนด established in 1960
ๅตๆฅญ ใใใใใ starting the business ๅตๆฅญๆๆฒป15ๅนด established in Meiji 15
