Does anybody use bloom nutes during veg under led? (Hlg scorpion, Mars hydro)

I’m coming across threads of people saying they fixed a lot of there slow growth simply by using bloom nutes in veg to boost p, I already use more cal mag and increase temperatures but my plants still desire something more Any thoughts?!

depends on how much nitrogen it has in it, grow nutes have more N for growth, but most use growth for growth stage.
is that all you have? you might get away putting the plants into flower at a young age and only useing flower nutes

No I do have ff trio, some calmag, inocculants some other stuff but I’m still getting purple stems that aren’t really going away with cal mag, in ffof

I do but i use hps and bio bizz and you mix the two accordingly to whatever ratio depending on what stage of growth you at you probably get away with it but feed light to be on the safe side
