Topping or not?

Hi there, You can top or fim when they have 4 or 5 nodes.It’s still alittle bit early to do that.But I recommend to do LST rather than topping or fimming.For an auto flower,you shouldn’t top or fim more than one time.They have very short life cycle and don’t have so much time to recover.You can get the same result or may be better one by doing LST.So I encourage you to do only LST rather than top or fim.Happy growing... ✌️

Give it at least one more node two would be better You can take it down to 3 if you wish then, you are actually waiting so the roots are big enough to make the stress more manageable for the plant.
