Symptoms Of Using Too much Phosphorus? (outdoor grow)

I have been using Maxsea 3-20-20 since my girls started flowering. I have been at least doubling the recommended dosage around once a week. Everything has looked great since I started feeding. Recently I have noticed, but I could be wrong, the buds seem to be getting smaller. The plants are not quite done, but they seem to have hit a wall the last couple of weeks. I haven't had any burning, PM, pest, etc. Any thoughts on why they might look smaller.....thanks

i used maxsea 3-20-20 this past grow (on the heavy side) as well. I noticed no ill effects, its a good product for a good price. Maybe your buds haven't reached the swell stage yet and your anticipating it early?

Thanks for the input
