@Tito_Yayo, Iβve done side by side plants. Topped and fimmed, yield was nearly equal. Topped buds larger and fuller, fimmed had a lot more buds sites with real respectable yield.
If it doesnβt take well, just top it. I prefer topping. Iβm really height limited. And fimming produces more foliage. Thatβs what I find anyway. With the quality of seed out there nowadays I really do find growing this stuff pretty easy. Wish the same for you.
