Burnt outout

OK so I've been growing my nirvana crystal for the for six weeks under a 400w MH. At the end of the 5th week my bulb was blown so I switched to my 400w HPS. My question is since I got a new MH bulb should I swith back and veg. Longer or just continue on with the grow under the HPS? as you can see the plant is short and squat instead of lanky!

You LED, bro?

HID

Did you switch the light schedule to 12/12? If so keep flowering it. If not just put the mh back in. Try flowering with the mh for fun sometime, you might get a frosty harvest.

No actually was going to veg for 8 weeks then swith its still on 18/6
