mmmm doubt it was isopropyl,. check out @Suds.an.buds grow he soaked his like 3 days in a row without covering the medium so some of the roots got burned and showed in the leaves,.. i forgot to tell him to cover his medium, look T his plants now,.. you wouldn’t know it,. their beautiful,. 5 weeks in flower,.
i just sprayed 26 clones barely rooted, everyone is fine,.. @Beachbumm just did his outdoor plants once and all cleaned,.. @BB22 might not of covered his medium and got it really soaked,..
it’s fine for plants,..
