Mimosa Cake Auto in mini grow led

Hi everyone, the plant has some deficiencies I suppose in nitrogen and magnesium, the dose of fertilizer was not sufficient even for a week, furthermore it grows very quickly. about 8 days ago I did some trimming and the plant developed some lateral branches, so I was able to start placing some stakes to proceed with the LST. I hope I have enough space, I started bending a little late. see you soon for updates.
