White widow height question

Hey folks getting concerned about my WW. I flowered about 40 days and switched when she was 18inches and pre flowered . I am now 30 day flowering under 400 hps using ff triple and she is only 32 Inches and growing very slow. Any suggestions why. I feed nutrients every other watering. And she also isn't using water very fast. Water about every 5 days when she dried out. Last one I grew was 5 foot.

it wont get much taller,you should have veged it longer,you may get a couple more inches,but id say shes about where shell stay,i grow outdoors mostly and last grow i only veged till about foot tall then put them outside,they only got to 25 inches,but,i got about 6.5 oz cured,and was all nice big fat buds,4 of which weiged from 20 to 24 grams,good luck,

Last time I vegged about the same and she grew to almost 5 feet and I got 6 oz off of her. Just threw me off when I realized she wasnt going to be that big this time. I guess time will tell..lol. Thanks for the response..that eases my mind a bit.
