Hey whisp so I think everythings worth a try because you'll only know for sure by testing. If you went against this, I'd definitely say to look into the approximate time that this strain starts flowering, 4week, 6week, and defoliate/ or chop right when flowering is beginning. I kept putting off my chops until too far into flowering in my opinion and feel like if the plant had been given the signal sooner it would have channeled that energy to the budsites much more effectively.
Since Dinafem is pretty solid and its an xxl version which i believe takes longer to finish, i dont think there'd be any harm in waiting a few weeks.
Sorry I don't have more experience with the low growth tip cutting, I do feel like a plant this young and healthy could manage to be topped effectively though too, so just possible ideas. ✌️ good luck.
