I started with Duolingo and while it has all the regular duo problems, I think it actually does a good job with the kana stuff. You can turn off the Romaji too, forcing yourself to read. It doesn't teach grammar, though, so I bought Genki Vol 1, working my way through that, and wotaku.wiki has a lot of good resources.

I really like the Cure Dolly stuff for grammar (though she can be difficult to understand, use the youtube transcripts or if you prefer reading a book someone helpfully wrote it all up). Her approach is totally different from the Genki methods, but I find it easier to understand.

I am also using Anki with the Kaishi 1.5k Kanji deck for kanji and vocabulary. This is honestly pretty painful, I've been doing it for like 10 days now and I feel like I'm doing badly every time, but I am improving. I could probably stand to study the radical stuff to understand more how the kanji is constructed but I haven't found a good resource for that just yet.
