week 1 veg

all of my plants the Pineapple chunk and northern lights are a week into veg at 18/6 and are just starting their 4th nodes at the base of all the nodes its starting leaves. i though this wouldn't happen for another week...? they are only 3-5 inches tall. should i start topping or is it to early? They are in Fox farm soil. under 4 ft. fluorescent cool whites. they look healthy as can be. any advice? it's my first grow ever indoors and am pretty new to the whole topping thing and i never checked on the ones i grew outdoors for weeks at a time.

id wait till it has about 6 nodes or so before id top em if i was to go that route.........

jesus... 5" after a week... nice!

I dont understand why alot of people top there plants... Id leave them be

yeah i never got that i either i normally just let them go

I like LST better than topping
