phosohorus issues

Hi I am having a phosphorus issues and need to know if I can treat from folior feeding. I just transplanted and watered with that has a ph of 6.5 so Im worried about over watering. I am currently in veg. I have mixed a weaker feeding of nutrients and plan to spray when the lights are off. Will this do harm? When the soil is dry I will continue with a normal feeding plan. Thanks for your help.

no it won't harm them. When your plant dries up, for the next watering give it a good flush.
