They look good brother.... the LST is always ok not going to hurt anything and very helpful with the taller girls...
Ahhhhh topping autos... this is a life long debate.... here's my 2 cents. all photo plants can be topped and recover because you can veg them longer..... SOME auto strains can be topped and increase there yield..... but SOME still don't have strong enough genetics to do so and yield is decreased.... that's where lst comes in.... SO LST your plants and never stunt and lower yield or top and take a chance that strain gets stunted... up to the grower but ide rather not waste 10 weeks and a 5 gallon pot in my tent on a stunted auto....
