Hey peggyO, so i think being three weeks they're not looking bad size wise...i think having growth spurts and slows is pretty common. With the flowering flip, if you continue to see slow growth, maybe up the night temps a bit, the slowed growth may he down to the topping..that can stall things briefly. also you'll maybe want to measure by size rather than time(weeks), check your available space and plan that the plant can double with the glowering stretch and flip when shes reached half the allowed space in the grow room. You may be able to use the space more with some lst or other training, but definitely plan on the double(and possibly more) in size when you do flip. Good luck with the grow ✌️

When to flip to flower is always a grower descision. Depending in what the Grower wants. Ive seen a documentation from commercial growers who let their plant 3 Weeks in vegetation (+1 week seedling) . They cut the Plant and let 3 Branches to Built Buds. That was very impressing. They got 40 cm high plants with 3 fat buds.Others let them 10 weeks while doing Mainlining. In your case , if you want to flip as soon as possible i would wait 2 more weeks, and in the meantime topping and supercropping them .First topping multiple and after switch supercropping.
