Well, that's really a topic that needs a second thought
In my humble opinion I'd like to say that anytime you get involved in teaching any subject and in this case English you must never focus your lessons mostly on grammar, and exercises realization, why?, where is the communicative approach of your lesson? Remember that there've always been misconceptions at the time of conducting an English lesson, misconceptions which not every teacher has, that have mislead the very own process a good example of this it's the ways many teachers of English teach by having their students become familiar with communicative functions, grammar and exercises. And it's not about that It's about making them speak, which is the most important. Remember that the four basic skills to be developed in your students are speaking, listening, reading and writing, and the most important which doesnot exclude the others is speaking. Have you ever noticed the lack of knowledge somehow natives have on grammar?, they don't know most of the time why they use a lot of words such as prepositions, and the like, they just use them, 'cause they learned to speak not to how to use the grammar related.
Practice, that is what our students need.
I agree that the inductive approach you used helped you students to gain practical knowledge of grammar directly from their own experience. Such approach must have also helped them to understand in which real-life situations they might apply this kind of knowledge. That is for sure one of the advantages of this approach.
On the other hand, you mentioned that some of your students needed more explicit explanation of grammar rules. Why do not give them additional home grammar exercises with the appropriate grammatical theory included and then discussed it online.
Teaching my students English Grammar, I often use the following structure:
In Class
1 – Oral practice of a number of grammar constructions. Rules are not explained. Situations, in which these grammar constructions are used, on the contrary, are well-explained and described.
2 – Small group performance of a short sketch that contains the same grammar.
3 - Discussion about the nature of grammar constructions just used.
At home
4 – Grammatical theory to be read and appropriate grammar exercises to be done.
5 – Online discussion if needed in order to gain more understanding.
