Hello friend,
I think some companies like fluence and bios light have really mastered the full spectrum that benefits all stages. But I've learned not all lights are created equally, especially older models.
I did a grow with 2 plants and 2 lights, 1 higher in red light and 1 blue/white, i never rotated the plants or switched them around, and the plant under the higher red performed incredibly better than the blue. Bigger buds, higher trichrome production and better smell etc.. I didn't understand this at 1st.
I think full spectrum lights are great, but i would opt for higher red lighting over blue/white in flower if you have to make a choice. Try checking the specifics of each light and find the one who has more of what you want.
I also believe that more light is usually better, so regardless of what's available if you can increase your lights without harming the plants I say go for it.
Happy growing ✌️
