Plants will not stop growing in veg,
I have a few questions...
Do you PH?
Are you introducing fresh air constantly?
Are your leaves looking flush amd healthy?
Do you have a timer?
Cannabis stores c02 in it's leaves and at "night time" it can quickly and easily replenish c02 deposits within the leaves.
Without fresh air, it is starving for carbon.
If your ph is out of order, it could be starving for nutrients.
What size light are you using?
Some growers use small lights to reduce growth of mother plants so that they don't grow unruly.
1. No i don't PH i used to but i was using the PH strips at first i did it all the time but it kept reading low PH and when i added nutrients it seemed to go up to a range where i liked it. I was also testing a theory i had that our water was fine for PH as i did some research state claims our water runs 7.0 when i tested with strips it wasn't 7.0 it was lower around 6.0 when i added nutrients it was 6.5 after this grow i WILL be getting a PH pen matter of fact i was actually gonna go to the gardening store today to buy one as i do plan to use it for my next grow but hell i can use it now even.
2. fresh air via outside through my windows only. if i am home i will open the closet door for about 5 hours per day then the rest of the day i close it so it does get some air but it's more heavily restricted.
3. besides for all my stupid little experiments i did on this grow like intentionally over feeding they seem alright. they are dark green and showing signs of nitrogen toxicity ( this seemed to stop ) some of the bottom foliage is turning yellow i am lost at whether it is because it is old, it is getting no light, or due to lack of feeding nitrogen for the past few weeks or even nitrogen toxicity ( looks like nitrogen deficiency to me though )
4. yes i just bought a timer yesterday.
im using King Plus 2000watt. tried looking up actual draw for these but i don't see anyone testing the actual draw so im basing it off what i found online which people claim 375, 385, company claims 392. they should still be growing though the plants are only about a 13 inches tall but very bushy from topping and LST
