I veg with cobs...small bushy plant... can I tie during flower PICTURE please help

Hello all

I go with one indica afghan kush plant in 35 l pot with 4 citizen diy 1212 gen 6 cobs

So I end with small bush plant that I pinch I now I can see 6 main colas all together...
I veg for 21 days and flip 4 days ago , so if I now start to train my plant for 2 weeks will it flower...
every time I tie for now the plant recovery very fast with this light...
So can I tie my plant in starting period of flowering, when to stop and what to add for food with this light...for now lux meter show avarage of 20 000 lux and watt meter for 4 cobs is 167 w...

Thank you very much

Alot of ak-kush varieties can stretch on me during flowering so i wouldn't worry too much.

3 weeks from sprout under good lights = short plant, more veg time or more plants would do nicely.

If i end up with short/bushy plants ill spread/tie them during atleast the first week of flowering.
