i have hps light about 6 inchs above my girl. I have a fan blowing on it at all times. The fan blows her around a lot. Is it ok for her to constantly be blown around? she is five days into flowering.

put the fan above the plant if you can and lift the light a bit maybe but a pic might help how big is your grow space?

Its a 400w hps and its as high as it can go. the box is 2x4x5. the plant is 3' and i have the fan positioned as best i can above her.

Wouldn't blowing a fan downward push the hottest air down as it tries to exit the ceiling of the project?
Grab an oscillating fan when you get a chance, then oscillate ( I have mine blowing between the fixtures and the canopies, on lo-med)

the fan is blowing in an upward direction and it is blowing between the light and the top. there is only 6 " between. I dont have a oscillating fan that will fit in the box.

Whats the temp at the top of the plant. I would think 6 inches is too close and you would burn your plant. measure temp at plant top with a thermometer. Keep it under 85 F if possible and to answer your first question yes its ok to let the fan blow on the plant all the time.
