Ok to use multiple fertilizers at once?

Hi all,

If you are growing in soil can you use multiple types of fertilizers in one watering? I am 2.5weeks into 12/12. I think my plants are suffering from overall lack of nutrients, I vegged with poor MG general plant/vegetable food. At 12/12 I repotted in fresh MG moisture control, steer manure compost (.5 - .5 - .5)and peat moss. I have a schultz bloomplus 10-54-10, and Alaska Morbloom 0-10-10.

Can I use both the blooming fertilizers or is there a benefit to doing it?

Never used those products before. But I use in half doses big bloom,tiger bloom,open sesame which would be around the same thing you are about to do. The only problem I had was with I fumbled some of the formulation and it hit the end of a fan leaf to cause a localized nutrient burn other than that everything else was cool and has been cool because been doing that for years.
